? 2012-2013 microchip technology inc. ds30009312b-page 13 PIC24FJ128GC010 family 1.0 device overview this document contains device-specific information for the following devices: the PIC24FJ128GC010 family expands the capabilities of the pic24f family by adding a complete selection of advanced analog peripherals to its existing digital fea- tures. this combination, along with its ultra low-power features, direct memory access (dma) for peripherals, usb on-the-go (otg) and a built-in lcd controller and driver, makes this family the new standard for mixed-signal pic ? microcontrollers in one economical and power-saving package. 1.1 core features 1.1.1 16-bit architecture central to all pic24f devices is the 16-bit modified harvard architecture, first introduced with microchip?s dspic ? digital signal controllers (dscs). the pic24f cpu core offers a wide range of enhancements, such as: ? 16-bit data and 24-bit address paths with the ability to move information between data and memory spaces ? linear addressing of up to 12 mbytes (program space) and 32 kbytes (data) ? a 16-element working register array with built-in software stack support ? a 17 x 17 hardware multiplier with support for integer math ? hardware support for 32 by 16-bit division ? an instruction set that supports multiple addressing modes and is optimized for high-level languages, such as ?c? ? operational performance up to 16 mips 1.1.2 xlp power-saving technology the PIC24FJ128GC010 family of devices introduces a greatly expanded range of power-saving operating modes for the ultimate in power conservation. the new modes include: ? retention sleep, with essential circuits being powered from a separate low-voltage regulator ? retention deep sleep, a lower power mode that maintains data ram for fast start-up ? deep sleep without rtcc, for the lowest possible power consumption under software control ?v bat mode (with or without rtcc), to continue limited operation from a backup battery when v dd is removed many of these new low-power modes also support the continuous operation of the low-power, on-chip real-time clock/calendar (rtcc), making it possible for an application to keep time while the device is otherwise asleep. aside from these new features, PIC24FJ128GC010 family devices also include all of the legacy power-saving features of previous pic24f microcontrollers, such as: ? on-the-fly clock switching, allowing the selection of a lower power clock during run time ? doze mode operation, for maintaining peripheral clock speed while slowing the cpu clock ? instruction-based power-saving modes, for quick invocation of idle and the many sleep modes. 1.1.3 oscillator options and features all of the devices in the PIC24FJ128GC010 family offer five different oscillator options, allowing users a range of choices in developing application hardware. these include: ? two crystal modes ? two external clock modes ? a phase lock loop (pll) frequency multiplier, which allows clock speeds of up to 32 mhz ? a fast internal oscillator (frc) ? nominal 8 mhz output, with multiple frequency divider options and automatic frequency self-calibration during run time ? a separate low-power internal rc oscillator (lprc) ? 31 khz nominal, for low-power, timing-insensitive applications. the internal oscillator block also provides a stable reference source for the fail-safe clock monitor (fscm). this option constantly monitors the main clock source against a reference signal provided by the inter- nal oscillator and enables the controller to switch to the internal oscillator, allowing for continued low-speed operation or a safe application shutdown. 1.1.4 easy migration regardless of the memory size, all devices share the same rich set of peripherals, allowing for a smooth migration path as applications grow and evolve. this extends the ability of applications to grow from the relatively simple, to the powerful and complex, while still selecting a microchip device. ? pic24fj64gc006 ? pic24fj128gc006 ? pic24fj64gc010 ?

PIC24FJ128GC010 family ds30009312b-page 14 ? 2012-2013 microchip technology inc. 1.2 advanced analog features the centerpiece of the PIC24FJ128GC010 family is the advanced analog block. this feature set provides appli- cation developers with all the tools they need for single chip applications that demand high analog performance. included in the advanced analog block are: ? a new 12-bit, pipelined a/d converter (a/d) module. a major departure from previous pic24f a/d converters, this module offers up to 50 single-ended input channels (or up to 25 differ- ential channel pairs) and conversion rates of up to ten million samples per second. it also provides a wider range of new features that allow the con- verter to assess and make decisions on incoming data without cpu intervention. ? a dual differential channel, sigma-delta a/d con- verter, for applications requiring high-precision conversions (up to 16-bit resolution). the sigma-delta converter also offers programmable gain on each channel pair, and user-configurable data rate, between 976 samples per second and 62.5 ksps. ? two independent, 10-bit digital-to-analog converters (dacs), each capable of conversion rates up to one million samples per second. ? a comparator module with three analog compara- tors that are configurable for a wide range of operations. the comparators also have their own independent, configurable voltage reference. ? a dual operational amplifier module with multiple input options, selectable power modes, and rail-to-rail operation on the inputs and outputs. each of the op amps can also be configured to function as a comparator, complete with interrupt generation. ? a dedicated, integrated band gap voltage refer- ence for all analog modules, providing a range of on-chip reference voltages and two buffered reference outputs. ? flexible multiplexing options for the entire analog block, allowing for the convenient sharing of signals between the analog modules. 1.3 dma controller PIC24FJ128GC010 family devices also add a direct memory access (dma) controller to the existing pic24f architecture. the dma acts in concert with the cpu, allowing data to move between data memory and peripherals without the intervention of the cpu, increasing data throughput, and decreasing execution time overhead. six independently programmable chan- nels make it possible to service multiple peripherals at virtually the same time, with each channel peripheral performing a different operation. many types of data transfer operations are supported. 1.4 usb on-the-go (otg) usb on-the-go provides on-chip functionality as a target device compatible with the usb 2.0 standard, as well as limited stand-alone functionality as a usb embedded host. by implementing usb host negotia- tion protocol (hnp), the module can also dynamically switch between device and host operation, allowing for a much wider range of versatile usb-enabled applications on a microcontroller platform. PIC24FJ128GC010 family devices also incorporate an integrated usb transceiver and precision oscillator, minimizing the required complexity of implementing a complete usb device, embedded host, dual role or on-the-go application. 1.5 lcd controller with the PIC24FJ128GC010 family of devices, microchip introduces its versatile liquid crystal display (lcd) controller and driver to the pic24f family. the on-chip lcd driver includes many features that make the integration of displays in low-power applications easier. these include an integrated voltage regulator with charge pump and an integrated internal resistor ladder that allows contrast control in software, and display operation above device v dd .
? 2012-2013 microchip technology inc. ds30009312b-page 15 PIC24FJ128GC010 family 1.6 other special features ? peripheral pin select (pps): the peripheral pin select feature allows most digital peripherals to be mapped over a fixed set of digital i/o pins. users may independently map the input and/or output of any one of the many digital peripherals to any one of the i/o pins. ? communications: the PIC24FJ128GC010 family incorporates several different serial communication peripherals to handle a range of application requirements. there are two indepen- dent i 2 c? modules that support both master and slave modes of operation. devices also have, through the pps feature, four independent uarts with built-in irda ? encoders/decoders and two spi modules. ? ctmu interface: in addition to their other analog features, members of the PIC24FJ128GC010 family include the ctmu interface module. this provides a convenient method for precision time measurement and pulse generation, and can serve as an interface for capacitive sensors. ? enhanced parallel master/parallel slave port: this module allows rapid and transparent access to the microcontroller data bus, and enables the cpu to directly address external data memory. the parallel port can function in master or slave mode, accommodating data widths of 4, 8 or 16 bits, and address widths of up to 23 bits in master modes. ? real-time clock and calendar (rtcc): this module implements a full-featured clock and calendar with alarm functions in hardware, freeing up timer resources and program memory space for use of the core application. ? data signal modulator (dsm): the data signal modulator (dsm) allows the user to mix a digital data stream (the ?modulator signal?) with a carrier signal to produce a modulated output. 1.7 details on individual family members devices in the PIC24FJ128GC010 family are available in 64-pin and 100/121-pin packages. the general block diagram for all devices is shown in figure 1-1 . the devices are differentiated from each other in six ways: 1. flash program memory (64 kbytes for pic24fj64gc0xx devices and 128 kbytes for pic24fj128gc0xx devices). 2. available i/o pins and ports (53 pins on 6 ports for 64-pin devices and 85 pins on 7 ports for 100/121-pin devices). 3. available interrupt-on-change notification (icn) inputs (52 on 64-pin devices and 82 on 100/121-pin devices). 4. available remappable pins (29 pins on 64-pin devices and 44 pins on 100/121-pin devices). 5. maximum available drivable lcd pixels (196 for 64-pin devices and 472 on 100/121-pin devices.) 6. analog input channels for the pipeline a/d converter (29 channels for 64-pin devices and 50 channels for 100/121-pin devices). all other features for devices in this family are identical. these are summarized in ta b l e 1 - 1 and tab l e 1 - 2 . a list of pin features available on the PIC24FJ128GC010 family devices, sorted by function, is shown in tab le 1 - 3 . note that this table shows the pin location of individual peripheral features and not how they are multiplexed on the same pin. this information is provided in the pinout diagrams in the beginning of the data sheet. multiplexed features are sorted by the priority given to a feature, with the highest priority peripheral being listed first.

PIC24FJ128GC010 family ds30009312b-page 36 ? 2012-2013 microchip technology inc. 2.4.1 considerations for ceramic capacitors in recent years, large value, low-voltage, surface-mount ceramic capacitors have become very cost effective in sizes up to a few tens of microfarad. the low-esr, small physical size and other properties make ceramic capacitors very attractive in many types of applications. ceramic capacitors are suitable for use with the inter- nal voltage regulator of this microcontroller. however, some care is needed in selecting the capacitor to ensure that it maintains sufficient capacitance over the intended operating range of the application. typical low-cost, 10 ? f ceramic capacitors are available in x5r, x7r and y5v dielectric ratings (other types are also available, but are less common). the initial toler- ance specifications for these types of capacitors are often specified as 10% to 20% (x5r and x7r), or -20%/+80% (y5v). however, the effective capacitance that these capacitors provide in an application circuit will also vary based on additional factors, such as the applied dc bias voltage and the temperature. the total in-circuit tolerance is, therefore, much wider than the initial tolerance specification. the x5r and x7r capacitors typically exhibit satisfac- tory temperature stability (ex: 15% over a wide temperature range, but consult the manufacturer?s data sheets for exact specifications). however, y5v capaci- tors typically have extreme temperature tolerance specifications of +22%/-82%. due to the extreme temperature tolerance, a 10 ? f nominal rated y5v type capacitor may not deliver enough total capacitance to meet minimum internal voltage regulator stability and transient response requirements. therefore, y5v capacitors are not recommended for use with the internal regulator if the application must operate over a wide temperature range. in addition to temperature tolerance, the effective capacitance of large value ceramic capacitors can vary substantially, based on the amount of dc voltage applied to the capacitor. this effect can be very signifi- cant, but is often overlooked or is not always documented. typical dc bias voltage vs. capacitance graph for x7r type capacitors is shown in figure 2-4 . figure 2-4: dc bias voltage vs. capacitance characteristics when selecting a ceramic capacitor to be used with the internal voltage regulator, it is suggested to select a high-voltage rating, so that the operating voltage is a small percentage of the maximum rated capacitor volt- age. for example, choose a ceramic capacitor rated at 16v for the 2.5v or 1.8v core voltage. suggested capacitors are shown in table 2-1 . 2.5 icsp pins the pgecx and pgedx pins are used for in-circuit serial programming (icsp) and debugging purposes. it is recommended to keep the trace length between the icsp connector and the icsp pins on the device as short as possible. if the icsp connector is expected to experience an esd event, a series resistor is recom- mended, with the value in the range of a few tens of ohms, not to exceed 100 ? . pull-up resistors, series diodes and capacitors on the pgecx and pgedx pins are not recommended as they will interfere with the programmer/debugger communi- cations to the device. if such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. alternatively, refer to the ac/dc characteristics and timing requirements information in the respective device flash programming specification for information on capacitive loading limits and pin voltage input high (v ih ) and voltage input low (v il ) requirements. for device emulation, ensure that the ?communication channel select? (i.e., pgecx/pgedx pins), programmed into the device, matches the physical connections for the icsp to the microchip debugger/emulator tool. the mclr connection from the icsp header should con- nect directly to the mclr pin on the device. a capacitor to ground (c1 in figure 2-2 ) is optional, but if used, may interfere with icsp operation if the value exceeds 0.01 ? f. in most cases, this capacitor is not required. for more information on available microchip development tools connection requirements, refer to section 35.0 ?development support? . -80 -70 -60 -50 -40 -30 -20 -10 0 10 5 1011121314151617 dc bias voltage (vdc) capacitance change (%) 01234 6789 16v capacitor 10v capacitor 6.3v capacitor

PIC24FJ128GC010 family ds30009312b-page 38 ? 2012-2013 microchip technology inc. 2.7 configuration of analog and digital pins during icsp operations if an icsp compliant emulator is selected as a debug- ger, it automatically initializes all of the a/d input pins (anx) as ?digital? pins. depending on the particular device, this is done by setting all bits in the adnpcfg register(s), or clearing all bit in the ansx registers. all pic24f devices will have either one or more adnpcfg registers or several ansx registers (one for each port); no device will have both. refer to section 11.2 ?configuring analog port pins (ansx)? for more specific information. the bits in these registers that correspond to the a/d pins that initialized the emulator must not be changed by the user application firmware; otherwise, communication errors will result between the debugger and the device. if your application needs to use certain a/d pins as analog input pins during the debug session, the user application must modify the appropriate bits during initialization of the a/d module, as follows: ? for devices with an adnpcfg register, clear the bits corresponding to the pin(s) to be configured as analog. do not change any other bits, particu- larly those corresponding to the pgecx/pgedx pair, at any time. ? for devices with ansx registers, set the bits corresponding to the pin(s) to be configured as analog. do not change any other bits, particularly those corresponding to the pgecx/pgedx pair, at any time. when a microchip debugger/emulator is used as a programmer, the user application firmware must correctly configure the adnpcfg or ansx registers. automatic initialization of this register is only done during debugger operation. failure to correctly configure the register(s) will result in all a/d pins being recognized as analog input pins, resulting in the port value being read as a logic ? 0 ?, which may affect user application functionality. 2.8 sigma-delta a/d connections the sigma-delta a/d converter has input and power connections that are independent from the rest of the microcontroller. these connections are required to use the converter, and are in addition to the connection and layout connections provided in section 2.1 ?basic connection requirements? and section 2.2 ?power supply pins? . 2.8.1 voltage and ground connections to minimize noise interference, the sigma-delta a/d converter has independent voltage pins. converter cir- cuits are supplied through the sv dd pin. independent ground return is provided through the svss pin. as with the microcontroller?s v dd /v ss and av dd /av ss pins, bypass capacitors are required on sv dd and sv ss . requirements for these capacitors are identical to those for the v dd /v ss and a vdd /av ss pins. it is recommended that designs using the sigma-delta a/d converter incorporate a separate ground return path for analog circuits. the analog and digital grounds may be tied to a single point at the power source. ana- log pins that require grounding should be tied to this analog return. sv ss can be tied to the digital ground, along with v ss and av ss . 2.8.2 analog inputs the analog signals to be converted are connected to the pins of ch0 and/or ch1. each channel has inverting and non-inverting inputs (chn- and chn+, respectively), and is fully differential. if not used for conversion, ch1+ and ch1- can be used to supply an external voltage reference to the con- verter. if an external reference is not used and ch1 is not needed as a conversion input, both pins should be connected to the analog ground return. 2.9 unused i/os unused i/o pins should be configured as outputs and driven to a logic low state. alternatively, connect a 1 k ? to 10 k ? resistor to v ss on unused pins and drive the output to logic low.
? 2012-2013 microchip technology inc. ds30009312b-page 39 PIC24FJ128GC010 family 3.0 cpu the pic24f cpu has a 16-bit (data) modified, harvard architecture with an enhanced instruction set and a 24-bit instruction word with a variable length opcode field. the program counter (pc) is 23 bits wide and addresses up to 4m instructions of user program memory space. a single-cycle instruction prefetch mechanism is used to help maintain throughput and provides predictable execution. all instructions execute in a single cycle, with the exception of instructions that change the program flow, the double-word move ( mov.d ) instruction and the table instructions. overhead-free program loop constructs are supported using the repeat instructions, which are interruptible at any point. pic24f devices have sixteen, 16-bit working registers in the programmer?s model. each of the working registers can act as a data, address or address offset register. the 16 th working register (w15) operates as a software stack pointer for interrupts and calls. the lower 32 kbytes of the data space can be accessed linearly. the upper 32 kbytes of the data space are referred to as extended data space to which the extended data ram, epmp memory space or program memory can be mapped. the instruction set architecture (isa) has been significantly enhanced beyond that of the pic18, but maintains an acceptable level of backward compatibil- ity. all pic18 instructions and addressing modes are supported, either directly, or through simple macros. many of the isa enhancements have been driven by compiler efficiency needs. the core supports inherent (no operand), relative, literal and memory direct addressing modes, along with three groups of addressing modes. all modes sup- port register direct and various register indirect modes. each group offers up to seven addressing modes. instructions are associated with predefined addressing modes, depending upon their functional requirements. for most instructions, the core is capable of executing a data (or program data) memory read, a working reg- ister (data) read, a data memory write and a program (instruction) memory read per instruction cycle. as a result, three parameter instructions can be supported, allowing trinary operations (that is, a + b = c) to be executed in a single cycle. a high-speed, 17-bit x 17-bit multiplier has been included to significantly enhance the core arithmetic capability and throughput. the multiplier supports signed, unsigned and mixed mode, 16-bit x 16-bit or 8-bit x 8-bit, integer multiplication. all multiply instructions execute in a single cycle. the 16-bit alu has been enhanced with integer divide assist hardware that supports an iterative non-restoring divide algorithm. it operates in conjunction with the repeat instruction looping mechanism and a selection of iterative divide instructions to support 32-bit (or 16-bit), divided by 16-bit, integer signed and unsigned division. all divide operations require 19 cycles to complete but are interruptible at any cycle boundary. the pic24f has a vectored exception scheme with up to 8 sources of non-maskable traps and up to 118 interrupt sources. each interrupt source can be assigned to one of seven priority levels. a block diagram of the cpu is shown in figure 3-1 . 3.1 programmer?s model the programmer?s model for the pic24f is shown in figure 3-2 . all registers in the programmer?s model are memory mapped and can be manipulated directly by instructions. a description of each register is provided in ta b l e 3 - 1 . all registers associated with the programmer?s model are memory mapped. note: this data sheet summarizes the features of this group of pic24f devices. it is not intended to be a comprehensive reference source. for more information, refer to the ?pic24f family reference manual? , ?cpu with extended data space (eds)?

PIC24FJ128GC010 family ds30009312b-page 46 ? 2012-2013 microchip technology inc. 4.1.1 program memory organization the program memory space is organized in word-addressable blocks. although it is treated as 24 bits wide, it is more appropriate to think of each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. the lower word always has an even address, while the upper word has an odd address ( figure 4-2 ). program memory addresses are always word-aligned on the lower word and addresses are incremented or decremented by two during code execution. this arrangement also provides compatibility with data memory space addressing and makes it possible to access data in the program memory space. 4.1.2 hard memory vectors all pic24f devices reserve the addresses between 000000h and 000200h for hard-coded program execu- tion vectors. a hardware reset vector is provided to redirect code execution from the default value of the pc on device reset to the actual start of code. a goto instruction is programmed by the user at 000000h with the actual address for the start of code at 000002h. pic24f devices also have two interrupt vector tables (ivts), located from 000004h to 0000ffh and 000100h to 0001ffh. these vector tables allow each of the many device interrupt sources to be handled by sepa- rate isrs. a more detailed discussion of the interrupt vector tables is provided in section 8.1 ?interrupt vector table? . 4.1.3 flash configuration words in PIC24FJ128GC010 family devices, the top four words of on-chip program memory are reserved for configura- tion information. on device reset, the configuration information is copied into the appropriate configuration register. the addresses of the flash configuration word for devices in the PIC24FJ128GC010 family are shown in table 4-1 . their location in the memory map is shown with the other memory vectors in figure 4-1 . the configuration words in program memory are a compact format. the actual configuration bits are mapped in several different regi sters in the configuration memory space. their order in the flash configuration words does not reflect a corresponding arrangement in the configuration space. additional details on the device configuration words are provided in section 34.0 ?special features? . table 4-1: flash configuration words for PIC24FJ128GC010 family devices figure 4-2: program memory organization device program memory (words) configuration word addresses pic24fj64gc0xx 22,016 00abf8h:00abfeh pic24fj128gc0xx 44,032 0157f8h:0157feh 0 8 16 pc address 0x000000 0x000002 0x000004 0x000006 23 00000000 00000000 00000000 00000000 program memory ?phantom? byte (read as ? 0 ?) least significant word most significant word instruction width 0x000001 0x000003 0x000005 0x000007 msw address (lsw address)
? 2012-2013 microchip technology inc. ds30009312b-page 47 PIC24FJ128GC010 family 4.2 data memory space the pic24f core has a 16-bit wide data memory space, addressable as a single linear range. the data space (ds) is accessed using two address generation units (agus), one each for read and write operations. the data space memory map is shown in figure 4-3 . the 16-bit wide data addresses in the data memory space point to bytes within the data space. this gives a ds address range of 64 kbytes or 32k words. the lower half (0000h to 7fffh) is used for implemented (on-chip) memory addresses. the upper half of data memory address space (8000h to ffffh) is used as a window into the extended data space (eds). this allows the microcontroller to directly access a greater range of data beyond the standard 16-bit address range. eds is discussed in detail in section 4.2.5 ?extended data space (eds)? . the lower half of ds is compatible with previous pic24f microcontrollers without eds. all PIC24FJ128GC010 family devices implement 8 kbytes of data ram in the lower half of the ds, from 0800h to 27ffh. 4.2.1 data space width the data memory space is organized in byte-addressable, 16-bit wide blocks. data is aligned in data memory and registers as 16-bit words, but all data space effective addresses (eas) resolve to bytes. the least significant bytes (lsbs) of each word have even addresses, while the most significant bytes (msbs) have odd addresses. figure 4-3: data space memory map fo r PIC24FJ128GC010 family devices note: this data sheet summarizes the features of this group of pic24f devices. it is not intended to be a comprehensive reference source. for more information, refer to the ? pic24f family reference manual ?, section 45. ?data memory with extended data space (eds) ?

PIC24FJ128GC010 family ds30009312b-page 48 ? 2012-2013 microchip technology inc. 4.2.2 data memory organization and alignment to maintain backward compatibility with pic ? mcus and improve data space memory usage efficiency, the pic24f instruction set supports both word and byte operations. as a consequence of byte accessibility, all ea calculations are internally scaled to step through word-aligned memory. for example, the core recognizes that post-modified register indirect addressing mode [ws++] will result in a value of ws + 1 for byte operations and ws + 2 for word operations. data byte reads will read the complete word, which contains the byte, using the lsb of any ea to deter- mine which byte to select. the selected byte is placed onto the lsb of the data path. that is, data memory and registers are organized as two parallel, byte-wide entities with shared (word) address decode but separate write lines. data byte writes only write to the corresponding side of the array or register which matches the byte address. all word accesses must be aligned to an even address. misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations or translating from 8-bit mcu code. if a misaligned read or write is attempted, an address error trap will be generated. if the error occurred on a read, the instruction underway is completed; if it occurred on a write, the instruction will be executed but the write will not occur. in either case, a trap is then executed, allow- ing the system and/or user to examine the machine state prior to execution of the address fault. all byte loads into any w register are loaded into the lsb. the most significant byte (msb) is not modified. a sign-extend ( se ) instruction is provided to allow users to translate 8-bit signed data to 16-bit signed values. alternatively, for 16-bit unsigned data, users can clear the msb of any w register by executing a zero-extend ( ze ) instruction on the appropriate address. although most instructions are capable of operating on word or byte data sizes, it should be noted that some instructions operate only on words. 4.2.3 near data space the 8-kbyte area between 0000h and 1fffh is referred to as the near data space. locations in this space are directly addressable via a 13-bit absolute address field within all memory direct instructions. the remainder of the data space is addressable indirectly. additionally, the whole data space is addressable using mov instructions, which support memory direct addressing with a 16-bit address field. 4.2.4 special function register (sfr) space the first 2 kbytes of the near data space, from 0000h to 07ffh, are primarily occupied with special function registers (sfrs). these are used by the pic24f core and peripheral modules for controlling the operation of the device. sfrs are distributed among the modules that they con- trol and are generally grouped together by module. much of the sfr space contains unused addresses; these are read as ? 0 ?. a diagram of the sfr space, showing where the sfrs are actually implemented, is shown in tab le 4 - 2 . each implemented area indicates a 32-byte region where at least one address is imple- mented as an sfr. a complete list of implemented sfrs, including their addresses, is shown in tables 4-3 through 4-39 . table 4-2: implemented regions of sfr data space sfr space address xx00 xx20 xx40 xx60 xx80 xxa0 xxc0 xxe0 000h core icn interrupts 100h timers ? capture compare ? 200h i 2 c? urt spi/urt ( 1 ) spi ? ? ?urt i/o 300h a/d dma ? 400h a/d dac ? ? ?usbs/dana ? 500h a/d ?lcd ? 600h epmp rtc/cmp ( 2 ) crc ? avr pps ? 700h ? ? system nvm/pmd ctm ? ? ? ? legend: ? = no implemented sfrs in this block; urt = uart; s/d = sigma-delta a/d; avr = analog reference note 1: this region includes registers for the op amp module. 2: this region includes registers for the digital signal modulator (dsm) module.

PIC24FJ128GC010 family ds30009312b-page 74 ? 2012-2013 microchip technology inc. 4.2.5 extended data space (eds) the extended data space (eds) allows pic24f devices to address a much larger range of data than would otherwise be possible with a 16-bit address range. eds includes any additional internal data mem- ory not directly accessible by the lower 32-kbyte data address space and any external memory through the enhanced parallel master port (epmp). in addition, eds also allows read access to the program memory space. this feature is called program space visibility (psv) and is discussed in detail in section 4.3.3 ?reading data from program memory using eds? . figure 4-4 displays the entire eds space. the eds is organized as pages, called eds pages, with one page equal to the size of the eds window (32 kbytes). a par- ticular eds page is selected through the data space read register (dsrpag) or data space write register (dswpag). for psv, only the dsrpag register is used. the combination of the dsrpag register value and the 16-bit wide data address forms a 24-bit effective address (ea). the data addressing range of PIC24FJ128GC010 family devices depends on the version of the enhanced parallel master port (epmp) implemented on a particu- lar device; this is, in turn, is a function of the device pin count. table 4-40 lists the total memory accessible by each of the devices in this family. for more details on accessing external memory using epmp, refer to the ? pic24f family reference manual ?, section 42. ?enhanced parallel master port (epmp)?

PIC24FJ128GC010 family ds30009312b-page 78 ? 2012-2013 microchip technology inc. 4.3 interfacing program and data memory spaces the pic24f architecture uses a 24-bit wide program space and 16-bit wide data space. the architecture is also a modified harvard scheme, meaning that data can also be present in the program space. to use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. aside from normal execution, the pic24f architecture provides two methods by which program space can be accessed during operation: ? using table instructions to access individual bytes or words anywhere in the program space ? remapping a portion of the program space into the data space (program space visibility) table instructions allow an application to read or write to small areas of the program memory. this makes the method ideal for accessing data tables that need to be updated from time to time. it also allows access to all bytes of the program word. the remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look-ups from a large table of static data. it can only access the least significant word of the program word. 4.3.1 addressing program space since the address ranges for the data and program spaces are 16 and 24 bits, respectively, a method is needed to create a 23-bit or 24-bit program address from 16-bit data registers. the solution depends on the interface method to be used. for table operations, the 8-bit table memory page address register (tblpag) is used to define a 32k word region within the program space. this is concatenated with a 16-bit ea to arrive at a full 24-bit program space address. in this format, the msbs of tblpag are used to determine if the operation occurs in the user memory (tblpag<7> = 0 ) or the configuration memory (tblpag<7> = 1 ). for remapping operations, the 10-bit extended data space read register (dsrpag) is used to define a 16k word page in the program space. when the most significant bit (msb) of the ea is ? 1 ?, and the msb (bit 9) of dsrpag is ? 1 ?, the lower 8 bits of dsrpag are con- catenated with the lower 15 bits of the ea to form a 23-bit program space address. the dsrpag<8> bit decides whether the lower word (when the bit is ? 0 ?) or the higher word (when the bit is ? 1 ?) of program memory is mapped. unlike table operations, this strictly limits remapping operations to the user memory area. table 4-42 and figure 4-8 show how the program ea is created for table operations, and remapping accesses from the data ea. here, p<23:0> refer to a program space word, whereas d<15:0> refer to a data space word. table 4-42: program space address construction access type access space program space address <23> <22:16> <15> <14:1> <0> instruction access (code execution) user 0 pc<22:1> 0 0xx xxxx xxxx xxxx xxxx xxx0 tblrd/tblwt (byte/word read/write) user tblpag<7:0> data ea<15:0> 0xxx xxxx xxxx xxxx xxxx xxxx configuration tblpag<7:0> data ea<15:0> 1xxx xxxx xxxx xxxx xxxx xxxx program space visibility (block remap/read) user 0 dsrpag<7:0> ( 2 ) data ea<14:0> ( 1 ) 0 xxxx xxxx xxx xxxx xxxx xxxx note 1: data ea<15> is always ? 1 ? in this case, but is not used in calculating the program space address. bit 15 of the address is dsrpag<0>. 2: dsrpag<9> is always ? 1 ? in this case. dsrpag<8> decides whether the lower word or higher word of program memory is read. when dsrpag<8> is ? 0 ?, the lower word is read and when it is ? 1 ?, the higher word is read.

(icsp?) ? run-time self-programming (rtsp) ? enhanced in-circuit serial programming (enhanced icsp) icsp allows a PIC24FJ128GC010 family device to be serially programmed while in the end application circuit. this is simply done with two lines for the programming clock and programming data (named pgecx and pgedx, respectively), and three other lines for power (v dd ), ground (v ss ) and master clear (mclr ). this allows customers to manufacture boards with unprogrammed devices and then program the microcontroller just before shipping the product. this also allows the most recent firmware or a custom firmware to be programmed. rtsp is accomplished using tblrd (table read) and tblwt (table write) instructions. with rtsp, the user may write program memory data in blocks of 64 instruc- tions (192 bytes) at a time and erase program memory in blocks of 512 instructions (1536 bytes) at a time. 6.1 table instructions and flash programming regardless of the method used, all programming of flash memory is done with the table read and write instructions. these allow direct read and write access to the program memory space from the data memory while the device is in normal operating mode. the 24-bit target address in the program memory is formed using the tblpag<7:0> bits and the effective address (ea) from a w register, specified in the table instruction, as shown in figure 6-1 . the tblrdl and the tblwtl instructions are used to read or write to bits<15:0> of program memory. tblrdl and tblwtl can access program memory in both word and byte modes. the tblrdh and tblwth instructions are used to read or write to bits<23:16> of program memory. tblrdh and tblwth can also access program memory in word or byte mode. figure 6-1: addressing for table registers note: this data sheet summarizes the features of this group of pic24f devices. it is not intended to be a comprehensive reference source. for more information, refer to the ?pic24f family reference manual? , ?program memory?

(parameter dc17b ). 7.4 clock source selection at reset if clock switching is enabled, the system clock source at device reset is chosen, as shown in table 7-2 . if clock switching is disabled, the system clock source is always selected according to the oscillator configuration bits. refer to the ? pic24f family reference manual ?, section 6.0 ?oscillator?

PIC24FJ128GC010 family devices implement non-maskable traps and unique interrupts. these are summarized in ta b l e 8 - 1 and tab l e 8 - 2 . 8.1.1 alternate interrupt vector ta b l e the alternate interrupt vector table (aivt) is located after the ivt, as shown in figure 8-1 . the altivt (intcon2<15>) control bit provides access to the aivt. if the altivt bit is set, all interrupt and exception processes will use the alternate vectors instead of the default vectors. the alternate vectors are organized in the same manner as the default vectors. the aivt supports emulation and debugging efforts by providing a means to switch between an application, and a support environment, without requiring the inter- rupt vectors to be reprogrammed. this feature also enables switching between applications for evaluation of different software algorithms at run time. if the aivt is not needed, the aivt should be programmed with the same addresses used in the ivt. 8.2 reset sequence a device reset is not a true exception because the interrupt controller is not involved in the reset process. the pic24f devices clear their registers in response to a reset, which forces the pc to zero. the micro- controller then begins program execution at location, 000000h. the user programs a goto instruction at the reset address, which redirects program execution to the appropriate start-up routine. note: this data sheet summarizes the features of this group of pic24f devices. it is not intended to be a comprehensive refer- ence source. for more information, refer to the ? pic24f family reference manual ?, ?interrupts?

? 2012-2013 microchip technology inc. ds30009312b-page 107 PIC24FJ128GC010 family 8.3 interrupt control and status registers the PIC24FJ128GC010 family of devices implements a total of 44 registers for the interrupt controller: ? intcon1 ? intcon2 ? ifs0 through ifs7 ? iec0 through iec7 ? ipc0 through ipc13, icp15, icp16, icp18 through icp23, icp25, icp26 and icp29 ?inttreg global interrupt control functions are controlled from intcon1 and intcon2. intcon1 contains the inter- rupt nesting disable (nstdis) bit, as well as the control and status flags for the processor trap sources. the intcon2 register controls the external interrupt request signal behavior and the use of the alternate interrupt vector table (aivt). the ifsx registers maintain all of the interrupt request flags. each source of interrupt has a status bit, which is set by the respective peripherals or an external signal and is cleared via software. the iecx registers maintain all of the interrupt enable bits. these control bits are used to individually enable interrupts from the peripherals or external signals. the ipcx registers are used to set the interrupt priority level (ipl) for each source of interrupt. each user interrupt source can be assigned to one of eight priority levels. the inttreg register contains the associated interrupt vector number and the new cpu interrupt priority level, which are latched into the vector number (vecnum<6:0>) and the interrupt level (ilr<3:0>) bit fields in the inttreg register. the new interrupt priority level is the priority of the pending interrupt. the interrupt sources are assigned to the ifsx, iecx and ipcx registers in the order of their vector numbers, as shown in tab l e 8 - 2 . for example, the int0 (external interrupt 0) is shown as having a vector number and a natural order priority of 0. thus, the int0if status bit is found in ifs0<0>, the int0ie enable bit in iec0<0> and the int0ip<2:0> priority bits in the first position of ipc0 (ipc0<2:0>). although they are not specifically part of the interrupt control hardware, two of the cpu control registers con- tain bits that control interrupt functionality. the alu status register (sr) contains the ipl<2:0> bits (sr<7:5>). these indicate the current cpu interrupt priority level. the user can change the current cpu priority level by writing to the iplx bits. the corcon register contains the ipl3 bit, which together with the ipl<2:0> bits, indicates the current cpu priority level. ipl3 is a read-only bit so that trap events cannot be masked by the user software. the interrupt controller has the interrupt controller test register, inttreg, which displays the status of the interrupt controller. when an interrupt request occurs, its associated vector number and the new interrupt pri- ority level are latched into inttreg. this information can be used to determine a specific interrupt source if a generic isr is used for multiple vectors (such as when isr remapping is used in bootloader applica- tions) or to check if another interrupt is pending while in an isr. all interrupt registers are described in register 8-1 through register 8-46 in the succeeding pages.

? 2012-2013 microchip technology inc. ds30009312b-page 165 PIC24FJ128GC010 family 9.4 clock switching operation with few limitations, applications are free to switch between any of the four clock sources (posc, sosc, frc and lprc) under software control and at any time. to limit the possible side effects that could result from this flexibility, pic24f devices have a safeguard lock built into the switching process. 9.4.1 enabling clock switching to enable clock switching, the fcksm1 configuration bit in cw2 must be programmed to ? 0 ?. (refer to section 34.1 ?configuration bits? for further details.) if the fcksm1 configuration bit is unprogrammed (? 1 ?), the clock switching function and fail-safe clock monitor function are disabled; this is the default setting. the noscx control bits (osccon<10:8>) do not control the clock selection when clock switching is disabled. however, the cosc<2:0> bits (osccon<14:12>) will reflect the clock source selected by the fnoscx configuration bits. the oswen control bit (osccon<0>) has no effect when clock switching is disabled; it is held at ? 0 ? at all times. 9.4.2 oscillator switching sequence at a minimum, performing a clock switch requires this basic sequence: 1. if desired, read the coscx bits (osccon<14:12>) to determine the current oscillator source. 2. perform the unlock sequence to allow a write to the osccon register high byte. 3. write the appropriate value to the noscx bits (osccon<10:8>) for the new oscillator source. 4. perform the unlock sequence to allow a write to the osccon register low byte. 5. set the oswen bit to initiate the oscillator switch. once the basic sequence is completed, the system clock hardware responds automatically as follows: 1. the clock switching hardware compares the coscx bits with the new value of the noscx bits. if they are the same, then the clock switch is a redundant operation. in this case, the oswen bit is cleared automatically and the clock switch is aborted. 2. if a valid clock switch has been initiated, the lock (osccon<5>) and cf (osccon<3>) bits are cleared. 3. the new oscillator is turned on by the hardware if it is not currently running. if a crystal oscillator must be turned on, the hardware will wait until the ost expires. if the new source is using the pll, then the hardware waits until a pll lock is detected (lock = 1 ). 4. the hardware waits for 10 clock cycles from the new clock source and then performs the clock switch. 5. the hardware clears the oswen bit to indicate a successful clock transition. in addition, the noscx bit values are transferred to the coscx bits. 6. the old clock source is turned off at this time, with the exception of lprc (if wdt or fscm is enabled) or sosc (if soscen remains set). note: the primary oscillator mode has three different submodes (xt, hs and ec) which are determined by the poscmdx configuration bits. while an application can switch to and from primary oscillator mode in software, it cannot switch between the different primary submodes without reprogramming the device. note 1: the processor will continue to execute code throughout the clock switching sequence. timing-sensitive code should not be executed during this time. 2: direct clock switches between any primary oscillator mode with pll and frcpll mode are not permitted. this applies to clock switches in either direc- tion. in these instances, the application must switch to frc mode as a transi- tional clock source between the two pll modes.
PIC24FJ128GC010 family ds30009312b-page 166 ? 2012-2013 microchip technology inc. a recommended code sequence for a clock switch includes the following: 1. disable interrupts during the osccon register unlock and write sequence. 2. execute the unlock sequence for the osccon high byte by writing 78h and 9ah to osccon<15:8> in two back-to-back instructions. 3. write the new oscillator source to the noscx bits in the instruction immediately following the unlock sequence. 4. execute the unlock sequence for the osccon low byte by writing 46h and 57h to osccon<7:0> in two back-to-back instructions. 5. set the oswen bit in the instruction immediately following the unlock sequence. 6. continue to execute code that is not clock-sensitive (optional). 7. invoke an appropriate amount of software delay (cycle counting) to allow the selected oscillator and/or pll to start and stabilize. 8. check to see if oswen is ? 0 ?. if it is, the switch was successful. if oswen is still set, then check the lock bit to determine the cause of the failure. the core sequence for unlocking the osccon register and initiating a clock switch is shown in example 9-1 . example 9-1: basic code sequence for clock switching 9.5 frc active clock tuning PIC24FJ128GC010 family devices include an automatic mechanism to calibrate the frc during run time. this system uses active clock tuning from a source of known accuracy to maintain the frc within a very narrow margin of its nominal 8 mhz frequency. this allows for a frequency accuracy that is well within the requirements of the ?usb 2.0 specification? , regarding full-speed usb devices. the self-tune system is controlled by the bits in the upper half of the osctun register. setting the sten bit (osctun<15>) enables the self-tuning feature, allowing the hardware to calibrate to a source selected by the stsrc bit (osctun<12>). when stsrc = 1 , the system uses the start-of-frame (sof) packets from an external usb host for its source. when stsrc = 0 , the system uses the crystal-controlled sosc for its calibration source. regardless of the source, the system uses the tun<5:0> bits (osctun<5:0>) to change the frc oscillator?s fre- quency. frequency monitoring and adjustment is dynamic, occurring continuously during run time. while the system is active, the tunx bits cannot be written to by software. the self-tune system can generate a hardware interrupt, fstif. the interrupt can result from a drift of the frc from the reference by greater than 0.2% in either direction, or whenever the frequency deviation is beyond the ability of the tunx bits to correct (i.e., greater than 1.5%). the stlock and stor status bits (osctun<11,9>) are used to indicate these conditions. the stlpol and storpol bits (osctun<10,8>) configure the fstif interrupt to occur in the presence or the absence of the conditions. it is the user?s respon- sibility to monitor both the stlock and stor bits to determine the exact cause of the interrupt. ;place the new oscillator selection in w0 ;oscconh (high byte) unlock sequence mov #oscconh, w1 mov #0x78, w2 mov #0x9a, w3 mov.b w2, [w1] mov.b w3, [w1] ;set new oscillator selection mov.b wreg, oscconh ;oscconl (low byte) unlock sequence mov #oscconl, w1 mov #0x46, w2 mov #0x57, w3 mov.b w2, [w1] mov.b w3, [w1] ;start oscillator switch operation bset osccon,#0 note: the self-tune feature maintains sufficient accuracy for operation in usb device mode. for applications that function as a usb host, a high-accuracy clock source (0.05%) is still required. note: to use the usb as a reference clock tuning source (stsrc = 1 ), the micro- controller must be configured for usb device operation and connected to a non-suspended usb host or hub port. if the sosc is to be used as the reference clock tuning source (stsrc = 0 ), the sosc must also be enabled for clock tuning to occur. note: the stlpol and storpol bits should be ignored when the self-tune system is disabled (sten = 0 ).

PIC24FJ128GC010 family devices use the same clock structure as most other pic24fj devices, but include a two-branch pll system to generate the two clock signals. the usb pll block is shown in figure 9-2 . in this system, the input from the primary oscillator is divided down by a pll prescaler to generate a 4 mhz output. this is used to drive an on-chip, 96 mhz pll frequency multiplier to drive the two clock branches. one branch uses a fixed, divide-by-2 frequency divider to generate the 48 mhz usb clock. the other branch uses a fixed, divide-by-3 frequency divider and configurable pll prescaler/divider to generate a range of system clock frequencies. the cpdiv<1:0> bits select the system clock speed; available clock options are listed in table 9-2 . the usb pll prescaler does not automatically sense the incoming oscillator frequency. the user must man- ually configure the pll divider to generate the required 4 mhz output, using the plldiv<3:0> configuration bits. this limits the choices for primary oscillator frequency to a total of 8 possibilities, shown in table 9-3 . table 9-2: system clock options during usb operation table 9-3: valid primary oscillator configurations for usb operations figure 9-2: pll block mcu clock division (cpdiv<1:0>) microcontroller clock frequency none ( 00 )32mhz ? 2 ( 01 )16mhz ? 4 ( 10 ) ( 1 ) 8mhz ? 8 ( 11 ) ( 1 ) 4mhz note 1: this is not compatible with usb operation. the usb module must be disabled to use this system clock option. input oscillator frequency clock mode pll division (plldiv<3:0>) 48 mhz ecpll ? 12 ( 0111 ) 32 mhz hspll, ecpll ? 8 ( 0110 ) 24 mhz hspll, ecpll ? 6 ( 0101 ) 20 mhz hspll, ecpll ? 5 ( 0100 ) 16 mhz hspll, ecpll ? 4 ( 0011 ) 12 mhz hspll, ecpll ? 3 ( 0010 ) 8 mhz ecpll, xtpll, frcpll ( 1 ) ? 2 ( 0001 ) 4 mhz ecpll, xtpll, frcpll ( 1 ) ? 1 ( 0000 ) note 1: this requires the use of the frc self-tune feature to maintain required clock accuracy. pll 96 mhz pll ? 2 prescaler 4 mhz cpu divider 48 mhz clock for usb module pll output for system clock cpdiv<1:0> plldiv<3:0> input from posc input from frc (note 1) (4 mhz or 8 mhz) 32 mhz 0111 0110 0101 0100 0011 0010 0001 0000 ? 12 ? 8 ? 8 ? 6 ? 5 ? 4 ? 3 ? 2 ? 1 ? 4 ? 2 ? 1 ? 3 00 01 10 11 note 1: this mux is controlled by the cosc<2:0> bits w hen running from the pll, or the nosc<2:0> bits when preparing to switch to the pll.

PIC24FJ128GC010 family devices manage power consumption with five strategies: ? instruction-based power reduction modes ? hardware-based power reduction features ? clock frequency control ? software controlled doze mode ? selective peripheral control in software combinations of these methods can be used to selectively tailor an application?s power consumption, while still maintaining critical application features, such as timing-sensitive communications. 10.1 overview of power-saving modes in addition to full-power operation, otherwise known as run mode, the PIC24FJ128GC010 family of devices offers three instruction-based power-saving modes and one hardware-based mode: ?idle ? sleep (sleep and low-voltage sleep) ? deep sleep (with and without retention) ?v bat (with and without rtcc) all four modes can be activated by powering down dif- ferent functional areas of the microcontroller, allowing progressive reductions of operating and idle power consumption. in addition, three of the modes can be tailored for more power reduction, at a trade-off of some operating features. ta b l e 1 0 - 1 lists all of the operating modes, in order of increasing power savings. table 10-2 summarizes how the microcontroller exits the different modes. specific information is provided in the following sections. table 10-1: operating modes for PIC24FJ128GC010 family devices note: this data sheet summarizes the features of this group of pic24fj devices. it is not intended to be a comprehensive reference source. for more information, refer to the ?pic24f family reference manual? , ?power-saving features with deep sleep?

? 2012-2013 microchip technology inc. ds30009312b-page 173 PIC24FJ128GC010 family 10.1.2 hardware-based power-saving mode the hardware-based v bat mode does not require any action by the user during code development. instead, it is a hardware design feature that allows the micro- controller to retain critical data (using the dsgprx registers) and maintain the rtcc when v dd is removed from the application. this is accomplished by supplying a backup power source to a specific power pin. v bat mode is described in more detail in section 10.5 ?vbat mode? . 10.1.3 low-voltage/retention regulator PIC24FJ128GC010 family devices incorporate a second on-chip voltage regulator, designed to provide power to select microcontroller features at 1.2v, nomi- nal. this regulator allows features, such as data ram and the wdt, to be maintained in power-saving modes where they would otherwise be inactive, or maintain them at a lower power than would otherwise be the case. the low-voltage/retention regulator is only available when sleep or deep sleep modes are invoked. it is controlled by the lpcfg configuration bit (cw1<10>) and in firmware by the reten bit (rcon<12>). lpcfg must be programmed (= 0 ) and the reten bit must be set (= 1 ) for the regulator to be enabled. 10.2 idle mode idle mode provides these features: ? the cpu will stop executing instructions. ? the wdt is automatically cleared. ? the system clock source remains active. by default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see section 10.8 ?selective peripheral module control? ). ? if the wdt or fscm is enabled, the lprc will also remain active. the device will wake from idle mode on any of these events: ? any interrupt that is individually enabled ? any device reset ? a wdt time-out on wake-up from idle, the clock is re-applied to the cpu and instruction execution begins immediately, starting with the instruction following the pwrsav instruction or the first instruction in the interrupt service routine (isr). 10.3 sleep mode sleep mode includes these features: ? the system clock source is shut down. if an on-chip oscillator is used, it is turned off. ? the device current consumption will be reduced to a minimum provided that no i/o pin is sourcing current. ? the i/o pin directions and states are frozen. ? the fail-safe clock monitor does not operate during sleep mode since the system clock source is disabled. ? the lprc clock will continue to run in sleep mode if the wdt or rtcc, with lprc as the clock source, is enabled. ? the wdt, if enabled, is automatically cleared prior to entering sleep mode. ? some device features or peripherals may continue to operate in sleep mode. this includes items, such as the input change notification (icn) on the i/o ports, or peripherals that use an external clock input. any peripheral that requires the system clock source for its operation will be disabled in sleep mode. the device will wake-up from sleep mode on any of these events: ? on any interrupt source that is individually enabled ? on any form of device reset ? on a wdt time-out on wake-up from sleep, the processor will restart with the same clock source that was active when sleep mode was entered. 10.3.1 low-voltage/retention sleep mode low-voltage/retention sleep mode functions as sleep mode with the same features and wake-up triggers. the difference is that the low-voltage/retention regula- tor allows core digital logic voltage (v core ) to drop to 1.2v nominal. this permits an incremental reduction of power consumption over what would be required if v core was maintained at a 1.8v (minimum) level. low-voltage sleep mode requires a longer wake-up time than sleep mode, due to the additional time required to bring v core back to 1.8v (known as t reg ). in addition, the use of the low-voltage/retention regula- tor limits the amount of current that can be sourced to any active peripherals, such as the rtcc/lcd, etc.
PIC24FJ128GC010 family ds30009312b-page 174 ? 2012-2013 microchip technology inc. 10.4 deep sleep mode deep sleep mode provides the lowest levels of power consumption available from the instruction-based modes. PIC24FJ128GC010 family devices have two deep sleep modes: legacy deep sleep, found in other pic24f devices, and retention deep sleep, described below. deep sleep modes have these features: ? the system clock source is shut down. if an on-chip oscillator is used, it is turned off. ? the device current consumption will be reduced to a minimum. ? the i/o pin directions and states are frozen. ? the fail-safe clock monitor does not operate during sleep mode since the system clock source is disabled. ? the lprc clock will continue to run in deep sleep mode if the wdt, or rtcc with lprc as the clock source, is enabled. ? the dedicated deep sleep wdt and bor systems, if enabled, are used. ? the rtcc and its clock source continue to run, if enabled. all other peripherals are disabled. entry into deep sleep mode is completely under software control. exit from the deep sleep modes can be triggered from any of the following events: ? por event ?mclr event ? rtcc alarm (if the rtcc is present) ? external interrupt 0 ? deep sleep watchdog timer (dswdt) time-out 10.4.1 retention deep sleep unlike deep sleep mode, retention deep sleep mode represents an incremental increase in power consump- tion. although it also allows the device to operate at a v core of 1.2v, the low-voltage/retention regulator is used in this mode to maintain the contents of the data ram, which slightly increases current consumption. maintaining data ram (including the sfrs) has sev- eral effects that make retention deep sleep different form deep sleep: ? the wake-up sources are the same as those for deep sleep mode. ? wake-up from retention deep sleep allows the device to resume its previous state and start code execution where it left off, instead of restarting at the reset vector (as with deep sleep). 10.4.2 entering deep sleep mode deep sleep mode is entered by setting the dsen bit in the dscon register and then executing a sleep command ( pwrsav #sleep_mode ) within one instruc- tion cycle to minimize the chance that deep sleep will be spuriously entered. if the low-voltage/retention regulator is already enabled, prior to setting the dsen bit, the device will enter retention deep sleep. if the pwrsav command is not given within one instruction cycle, the dsen bit will be cleared by the hardware and must be set again by the software before entering deep sleep mode. the dsen bit is also automatically cleared when exiting deep sleep mode. the sequence to enter deep sleep mode is: 1. if the application requires the deep sleep wdt, enable it and configure its clock source. for more information on deep sleep wdt, see section 10.4.6 ?deep sleep wdt? . 2. if the application requires deep sleep bor, enable it by programming the dsboren configuration bit (cw4<6>). 3. if the application requires wake-up from deep sleep on rtcc alarm, enable and configure the rtcc module. for more information on rtcc, see section 23.0 ?real-time clock and calendar (rtcc)? . 4. if needed, save any critical application context data by writing it to the dsgpr0 and dsgpr1 registers (optional). 5. enable deep sleep mode by setting the dsen bit (dscon<15>). 6. enter deep sleep mode by issuing 3 nop commands and then a pwrsav #0 instruction. note: to re-enter deep sleep after a deep sleep wake-up, allow a delay of at least 3 t cy after clearing the release bit. note: a repeat sequence is required to set the dsen bit. the repeat sequence (repeating the instruction twice) is required to write to any of the deep sleep registers (dscon, dswake, dsgpr0, dsgpr1). this is required to prevent the user from entering deep sleep by mistake. any write to these registers has to be done twice to actually complete the write (see example 10-2 ).
? 2012-2013 microchip technology inc. ds30009312b-page 175 PIC24FJ128GC010 family any time the dsen bit is set, all bits in the dswake register will be automatically cleared. example 10-2: the repeat sequence 10.4.3 exiting deep sleep modes deep sleep modes exit on any one of the following events: ? por event on v dd supply. if there is no dsbor circuit to re-arm the v dd supply por circuit, the external v dd supply must be lowered to the natural arming voltage of the por circuit. ? dswdt time-out. when the dswdt timer times out, the device exits deep sleep. ? rtcc alarm (if rtcen = 1 ). ? assertion (? 0 ?) of the mclr pin. ? assertion of the int0 pin (if the interrupt was enabled before deep sleep mode was entered). the polarity configuration is used to determine the assertion level (? 0 ? or ? 1 ?) of the pin that will cause an exit from deep sleep mode. exiting from deep sleep mode requires a change on the int0 pin while in deep sleep mode. exiting deep sleep generally does not retain the state of the device and is equivalent to a power-on reset (por) of the device. exceptions to this include the rtcc (if present), which remains operational through the wake-up, the dsgprx registers and dswdt. wake-up events that occur from the time deep sleep exits, until the time the por sequence completes, are not ignored. the dswake register will capture all wake-up events, from setting dsen to clearing release. the sequence for exiting deep sleep mode is: 1. after a wake-up event, the device exits deep sleep and performs a por. the dsen bit is cleared automatically. code execution resumes at the reset vector. 2. to determine if the device exited deep sleep, read the deep sleep bit, dpslp (rcon<10>). this bit will be set if there was an exit from deep sleep mode. if the bit is set, clear it. 3. determine the wake-up source by reading the dswake register. 4. determine if a dsbor event occurred during deep sleep mode by reading the dsbor bit (dscon<1>). 5. if application context data has been saved, read it back from the dsgpr0 and dsgpr1 registers. 6. clear the release bit (dscon<0>). 10.4.4 saving context data with the dsgprx registers as exiting deep sleep mode causes a por, most special function registers reset to their default por values. in addition, because v core power is not sup- plied in deep sleep mode, information in data ram may be lost when exiting this mode. applications which require critical data to be saved, prior to deep sleep, may use the deep sleep general purpose registers, dsgpr0 and dsgpr1, or data eeprom (if available). unlike other sfrs, the con- tents of these registers are preserved while the device is in deep sleep mode. after exiting deep sleep, software can restore the data by reading the registers and clearing the release bit (dscon<0>). 10.4.5 i/o pins in deep sleep modes during deep sleep, the general purpose i/o pins retain their previous states and the secondary oscillator (sosc) will remain running, if enabled. pins that are configured as inputs (trisx bit set), prior to entry into deep sleep, remain high-impedance during deep sleep. pins that are configured as outputs (trisx bit clear), prior to entry into deep sleep, remain as output pins during deep sleep. while in this mode, they continue to drive the output level determined by their corresponding latx bit at the time of entry into deep sleep. note: any interrupt pending when entering deep sleep mode is cleared. example 1: mov #8000, w2 ; enable ds mov w2, dscon mov w2, dscon ; second write required to actually write to dscon example 2: bset dscon, #15 nop nop nop bset dscon, #15 ; enable ds (two writes required)
PIC24FJ128GC010 family ds30009312b-page 176 ? 2012-2013 microchip technology inc. once the device wakes back up, all i/o pins continue to maintain their previous states, even after the device has finished the por sequence and is executing application code again. pins configured as inputs during deep sleep remain high-impedance and pins configured as outputs continue to drive their previous value. after waking up, the tris and lat registers, and the soscen bit (osccon<1>), are reset. if firmware modifies any of these bits or registers, the i/o will not immediately go to the newly configured states. once the firmware clears the release bit (dscon<0>), the i/o pins are ?released?. this causes the i/o pins to take the states configured by their respective trisx and latx bit values. this means that keeping the sosc running after waking up requires the soscen bit to be set before clearing release. if the deep sleep bor (dsbor) is enabled, and a dsbor or a true por event occurs during deep sleep, the i/o pins will be immediately released, similar to clearing the release bit. all previous state information will be lost, including the general purpose dsgpr0 and dsgpr1 contents. if a mclr reset event occurs during deep sleep, the dsgprx, dscon and dswake registers will remain valid, and the release bit will remain set. the state of the sosc will also be retained. the i/o pins, however, will be reset to their mclr reset state. since release is still set, changes to the soscen bit (osccon<1>) cannot take effect until the release bit is cleared. in all other deep sleep wake-up cases, application firmware must clear the release bit in order to reconfigure the i/o pins. 10.4.6 deep sleep wdt to enable the dswdt in deep sleep mode, program the configuration bit, dswdten (cw4<7>). the device wdt need not be enabled for the dswdt to function. entry into deep sleep modes automatically resets the dswdt. the dswdt clock source is selected by the dswdtosc configuration bit (cw4<5>). the posts- caler options are programmed by the dswdps<4:0> configuration bits (cw4<4:0>). the minimum time-out period that can be achieved is 1 ms and the maximum is 25.7 days. for more details on dswdt configuration options, refer to section 34.0 ?special features? . 10.4.6.1 switching clocks in deep sleep mode both the rtcc and the dswdt may run from either sosc or the lprc clock source. this allows both the rtcc and dswdt to run without requiring both the lprc and sosc to be enabled together, reducing power consumption. running the rtcc from lprc will result in a loss of accuracy in the rtcc, of approximately 5 to 10%. if a more accurate rtcc is required, it must be run from the sosc clock source. the rtcc clock source is selected with the rtclk<1:0> bits (rtcpwc<11:10>). under certain circumstances, it is possible for the dswdt clock source to be off when entering deep sleep mode. in this case, the clock source is turned on automatically (if dswdt is enabled) without the need for software intervention. however, this can cause a delay in the start of the dswdt counters. in order to avoid this delay when using sosc as a clock source, the application can activate sosc prior to entering deep sleep mode. 10.4.7 checking and clearing the status of deep sleep upon entry into deep sleep mode, the status bit, dpslp (rcon<10>), becomes set and must be cleared by the software. on power-up, the software should read this status bit to determine if the reset was due to an exit from deep sleep mode and clear the bit if it is set. of the four possible combinations of dpslp and por bit states, three cases can be considered: ? both the dpslp and por bits are cleared. in this case, the reset was due to some event other than a deep sleep mode exit. ? the dpslp bit is clear, but the por bit is set; this is a normal por. ? both the dpslp and por bits are set. this means that deep sleep mode was entered, the device was powered down and deep sleep mode was exited. 10.4.8 power-on resets (pors) v dd voltage is monitored to produce pors. since exiting from deep sleep mode functionally looks like a por, the technique described in section 10.4.7 ?checking and clearing the status of deep sleep? should be used to distinguish between deep sleep and a true por event. when a true por occurs, the entire device, including all deep sleep logic (deep sleep registers, rtcc, dswdt, etc.), is reset.
? 2012-2013 microchip technology inc. ds30009312b-page 177 PIC24FJ128GC010 family 10.5 v bat mode this mode represents the lowest power state that the microcontroller can achieve and still resume operation. v bat mode is automatically triggered when the micro- controller?s main power supply on v dd fails. when this happens, the microcontroller?s on-chip power switch connects to a backup power source, such as a battery, supplied to the v bat pin. this maintains a few key systems at an extremely low-power draw until v dd is restored. the power supplied on v bat only runs two systems: the rtcc and the deep sleep semaphore registers (dsgpr0 and dsgpr1). to maintain these systems during a sudden loss of v dd , it is essential to connect a power source, other than v dd or av dd , to the v bat pin. when the rtcc is enabled, it continues to operate with the same clock source (sosc or lprc) that was selected prior to entering v bat mode. there is no pro- vision to switch to a lower power clock source after the mode switch. since the loss of v dd is usually an unforeseen event, it is recommended that the contents of the deep sleep semaphore registers be loaded with the data to be retained at an early point in code execution. 10.5.1 v bat mode with no rtcc by disabling rtcc operation during v bat mode, power consumption is reduced to the lowest of all power-saving modes. this is done by programming the rtcbat configuration bit (cw4<9>) to ? 0 ?. in this mode, only the deep sleep semaphore registers are maintained. 10.5.2 wake-up from v bat modes when v dd is restored to a device in v bat mode, it auto- matically wakes. wake-up occurs with a por, after which, the device starts executing code from the reset vector. all sfrs, except the deep sleep semaphore registers, are reset to their por values. if the rtcc was not configured to run during v bat mode, it will remain disabled and rtcc will not run. wake-up timing is similar to that for a normal por. to differentiate a wake-up from v bat mode from other por states, check the vbat status bit (rcon2<0>). if this bit is set while the device is starting to execute the code from the reset vector, it indicates that there has been an exit from v bat mode. the application must clear the vbat bit to ensure that future v bat wake-up events are captured. if a por occurs without a power source connected to the v bat pin, the vbpor bit (rcon2<1>) is set. if this bit is set on a por, it indicates that a battery needs to be connected to the v bat pin. in addition, if the v bat power source falls below the level needed for deep sleep semaphore operation while in v bat mode (e.g., the battery has been drained), the vbpor bit will be set. vbpor is also set when the microcontroller is powered up the very first time, even if power is supplied to v bat . 10.5.3 i/o pins during v bat modes all i/o pins switch to input mode during v bat mode. the only exceptions are the sosci and sosco pins, which maintain their states if the secondary oscillator is being used as the rtcc clock source. it is the user?s responsibility to restore the i/o pins to their proper states, using the trisx and latx bits, once v dd has been restored. 10.5.4 saving context data with the dsgprx registers as with deep sleep mode (i.e., without the low-voltage/retention regulator), all sfrs are reset to their por values after v dd has been restored. only the deep sleep semaphore registers are preserved. appli- cations which require critical data to be saved should save it in dsgpr0 and dsgpr1. the por should be enabled for the reliable operation of the v bat . note: if the v bat mode is not used, it is recommended to connect the v bat pin to v dd .

PIC24FJ128GC010 family ds30009312b-page 192 ? 2012-2013 microchip technology inc. 11.4 peripheral pin select (pps) a major challenge in general purpose devices is provid- ing the largest possible set of peripheral features while minimizing the conflict of features on i/o pins. in an application that needs to use more than one peripheral multiplexed on a single pin, inconvenient work arounds in application code, or a complete redesign, may be the only option. the peripheral pin select (pps) feature provides an alternative to these choices by enabling the user?s peripheral set selection and its placement on a wide range of i/o pins. by increasing the pinout options available on a particular device, users can better tailor the microcontroller to their entire application, rather than trimming the application to fit the device. the peripheral pin select feature operates over a fixed subset of digital i/o pins. users may independently map the input and/or output of any one of many digital peripherals to any one of these i/o pins. pps is per- formed in software and generally does not require the device to be reprogrammed. hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once it has been established. 11.4.1 available pins the pps feature is used with a range of up to 44 pins, depending on the particular device and its pin count. pins that support the peripheral pin select feature include the designation, ?rpn? or ?rpin?, in their full pin designation, where ?n? is the remappable pin number. ?rp? is used to designate pins that support both remap- pable input and output functions, while ?rpi? indicates pins that support remappable input functions only. PIC24FJ128GC010 family devices support a larger number of remappable input only pins than remappable input/output pins. in this device family, there are up to 32 remappable input/output pins, depending on the pin count of the particular device selected. these pins are numbered, rp0 through rp31. remappable input only pins are numbered above this range, from rpi32 to rpi43 (or the upper limit for that particular device). see ta bl e 1 - 3 for a summary of pinout options in each package offering. 11.4.2 available peripherals the peripherals managed by the pps are all digital only peripherals. these include general serial commu- nications (uart and spi), general purpose timer clock inputs, timer related peripherals (input capture and out- put compare) and external interrupt inputs. also included are the outputs of the comparator module, since these are discrete digital signals. pps is not available for these peripherals: ?i 2 c? (input and output) ? usb (all module inputs and outputs) ? change notification inputs ? rtcc alarm output(s) ? epmp signals (input and output) ? lcd signals ? analog (inputs and outputs) ?int0 a key difference between pin select and non-pin select peripherals is that pin select peripherals are not asso- ciated with a default i/o pin. the peripheral must always be assigned to a specific i/o pin before it can be used. in contrast, non-pin select peripherals are always available on a default pin, assuming that the peripheral is active and not conflicting with another peripheral. 11.4.2.1 peripheral pin select function priority pin-selectable peripheral outputs (e.g., oc, uart transmit) will take priority over general purpose digital functions on a pin, such as epmp and port i/o. special- ized digital outputs (e.g., usb on usb-enabled devices) will take priority over pps outputs on the same pin. the pin diagrams list peripheral outputs in the order of priority. refer to them for priority concerns on a particular pin. unlike pic24f devices with fixed peripherals, pin-selectable peripheral inputs will never take owner- ship of a pin. the pin?s output buffer will be controlled by the trisx setting or by a fixed peripheral on the pin. if the pin is configured in digital mode, then the pps input will operate correctly. if an analog function is enabled on the pin, the pps input will be disabled. 11.4.3 controlling peripheral pin select pps features are controlled through two sets of special function registers (sfrs): one to map peripheral inputs and one to map the outputs. because they are separately controlled, a particular peripheral?s input and output (if the peripheral has both) can be placed on any selectable function pin without constraint. the association of a peripheral to a peripheral-selectable pin is handled in two different ways, depending on if an input or an output is being mapped.

PIC24FJ128GC010 family ds30009312b-page 196 ? 2012-2013 microchip technology inc. 11.4.5 considerations for peripheral pin selection the ability to control peripheral pin selection intro- duces several considerations into application design that could be overlooked. this is particularly true for several common peripherals that are available only as remappable peripherals. the main consideration is that the peripheral pin selects are not available on default pins in the device?s default (reset) state. since all rpinrx registers reset to ? 111111 ? and all rporx registers reset to ? 000000 ?, all peripheral pin select inputs are tied to v ss and all peripheral pin select outputs are disconnected. this situation requires the user to initialize the device with the proper peripheral configuration before any other application code is executed. since the iolock bit resets in the unlocked state, it is not necessary to execute the unlock sequence after the device has come out of reset. for application safety, however, it is best to set iolock and lock the configuration after writing to the control registers. because the unlock sequence is timing-critical, it must be executed as an assembly language routine in the same manner as changes to the oscillator configura- tion. if the bulk of the application is written in ?c?, or another high-level language, the unlock sequence should be performed by writing in-line assembly. choosing the configuration requires a review of all peripheral pin selects and their pin assignments, especially those that will not be used in the application. in all cases, unused pin-selectable peripherals should be disabled completely. unused peripherals should have their inputs assigned to an unused rpn/rpin pin function. i/o pins with unused rpn functions should be configured with the null peripheral output. the assignment of a peripheral to a particular pin does not automatically perform any other configuration of the pin?s i/o circuitry. in theory, this means adding a pin-selectable output to a pin may mean inadvertently driving an existing peripheral input when the output is driven. users must be familiar with the behavior of other fixed peripherals that share a remappable pin and know when to enable or disable them. to be safe, fixed digital peripherals that share the same pin should be disabled when not in use. along these lines, configuring a remappable pin for a specific peripheral does not automatically turn that feature on. the peripheral must be specifically config- ured for operation and enabled as if it were tied to a fixed pin. where this happens in the application code (immediately following a device reset and peripheral configuration or inside the main application routine) depends on the peripheral and its use in the application. a final consideration is that peripheral pin select func- tions neither override analog inputs nor reconfigure pins with analog functions for digital i/o. if a pin is configured as an analog input on device reset, it must be explicitly reconfigured as digital i/o when used with a peripheral pin select. example 11-3 shows a configuration for bidirectional communication with flow control using uart1. the following input and output functions are used: ? input functions: u1rx, u1cts ? output functions: u1tx, u1rts example 11-3: configuring uart1 input and output functions note: in tying peripheral pin select inputs to rp63, the rp63 pin need not exist on a device for the registers to be reset to it. // unlock registers asm volatile ("mov #osccon, w1 \n" "mov #0x46, w2 \n" "mov #0x57, w3 \n" "mov.b w2, [w1] \n" "mov.b w3, [w1] \n" "bclr osccon, #6") ; // or use c30 built-in macro: // __builtin_write_oscconl(osccon & 0xbf); // configure input functions ( table 11-2 )) // assign u1rx to pin rp0 rpinr18bits.u1rxr = 0; // assign u1cts to pin rp1 rpinr18bits.u1ctsr = 1; // configure output functions ( table 11-4 ) // assign u1tx to pin rp2 rpor1bits.rp2r = 3; // assign u1rts to pin rp3 rpor1bits.rp3r = 4; // lock registers asm volatile ("mov #osccon, w1 \n" "mov #0x46, w2 \n" "mov #0x57, w3 \n" "mov.b w2, [w1] \n" "mov.b w3, [w1] \n" "bset osccon, #6"); // or use c30 built-in macro: // __builtin_write_oscconl(osccon | 0x40);

PIC24FJ128GC010 family ds30009312b-page 224 ? 2012-2013 microchip technology inc. 14.1.2 cascaded (32-bit) mode by default, each module operates independently with its own 16-bit timer. to increase resolution, adjacent even and odd modules can be configured to function as a single 32-bit module. (for example, modules 1 and 2 are paired, as are modules 3 and 4, and so on.) the odd numbered module (icx) provides the least signif- icant 16 bits of the 32-bit register pairs and the even module (icy) provides the most significant 16 bits. wrap-arounds of the icx registers cause an increment of their corresponding icy registers. cascaded operation is configured in hardware by setting the ic32 bits (icxcon2<8>) for both modules. 14.2 capture operations the input capture module can be configured to capture timer values and generate interrupts on rising edges on icx or all transitions on icx. captures can be config- ured to occur on all rising edges or just some (every 4 th or 16 th ). interrupts can be independently configured to generate on each event or a subset of events. to set up the module for capture operations: 1. configure the icx input for one of the available peripheral pin select pins. 2. if synchronous mode is to be used, disable the sync source before proceeding. 3. make sure that any previous data has been removed from the fifo by reading icxbuf until the icbne bit (icxcon1<3>) is cleared. 4. set the syncsel<4:0> bits (icxcon2<4:0>) to the desired sync/trigger source. 5. set the ictsel<2:0> bits (icxcon1<12:10>) for the desired clock source. 6. set the ici<1:0> bits (icxcon1<6:5>) to the desired interrupt frequency 7. select synchronous or trigger mode operation: a) check that the syncselx bits are not set to ? 00000 ?. b) for synchronous mode, clear the ictrig bit (icxcon2<7>). c) for trigger mode, set ictrig and clear the trigstat bit (icxcon2<6>). 8. set the icm<2:0> bits (icxcon1<2:0>) to the desired operational mode. 9. enable the selected sync/trigger source. for 32-bit cascaded operations, the setup procedure is slightly different: 1. set the ic32 bits for both modules (icy- con2<8>) and (icxcon2<8>), enabling the even numbered module first. this ensures the modules will start functioning in unison. 2. set the ictselx and syncselx bits for both modules to select the same sync/trigger and time base source. set the even module first, then the odd module. both modules must use the same ictselx and syncselx bits settings. 3. clear the ictrig bit of the even module (icy- con2<7>). this forces the module to run in synchronous mode with the odd module, regardless of its trigger setting. 4. use the odd module?s icix bits (icxcon1<6:5>) to set the desired interrupt frequency. 5. use the ictrig bit of the odd module (icx- con2<7>) to configure trigger or synchronous mode operation. 6. use the icmx bits of the odd module (icx- con1<2:0>) to set the desired capture mode. the module is ready to capture events when the time base and the sync/trigger source are enabled. when the icbne bit (icxcon1<3>) becomes set, at least one capture value is available in the fifo. read input capture values from the fifo until the icbne clears to ? 0 ?. for 32-bit operation, read both the icxbuf and icybuf for the full 32-bit timer value (icxbuf for the lsw, icybuf for the msw). at least one capture value is available in the fifo buffer when the odd module?s icbne bit (icxcon1<3>) becomes set. continue to read the buffer registers until icbne is cleared (performed automatically by hardware). note: for synchronous mode operation, enable the sync source as the last step. both input capture modules are held in reset until the sync source is enabled.

(for example, modules 1 and 2 are paired, as are modules 3 and 4, and so on.) the odd numbered module (ocx) provides the least significant 16 bits of the 32-bit register pairs and the even numbered module (ocy) provides the most significant 16 bits. wrap-arounds of the ocx registers cause an increment of their corresponding ocy registers. cascaded operation is configured in hardware by set- ting the oc32 bit (ocxcon2<8>) for both modules. for more details on cascading, refer to the ? pic24f family reference manual ?, section 35. ?output compare with dedicated timer?

(no sync/trigger source). 8. select the time base source with the octsel<2:0> bits. if necessary, set the ton bit for the selected timer, which enables the com- pare time base to count. synchronous mode operation starts as soon as the time base is enabled; trigger mode operation starts after a trigger source event occurs. comparator ocxtmr ocxcon1 ocxcon2 ocx interrupt ocx pin (1) comparator match event match event trigger and sync logic clock select increment reset oc clock sources trigger and sync sources reset match event ocfa/ocfb (2) octselx syncselx trigstat trigmode octrig ocmx ocinv octris fltout flttrien fltmd enflt<2:0> ocflt<2:0> note 1: the ocx outputs must be assigned to an available rpn pin before use. see section 11.4 ?peripheral pin select (pps)? for more information. 2: the ocfa/ocfb fault inputs must be assigned to an available rpn/rpin pin before use. see section 11.4 ?peripheral pin select (pps)? for more information. dcb<1:0> oc output and fault logic ocxr and dcb<1:0> ocxrs

? 2012-2013 microchip technology inc. ds30009312b-page 237 PIC24FJ128GC010 family 16.0 serial peripheral interface (spi) the serial peripheral interface (spi) module is a synchronous serial interface useful for communicating with other peripheral or microcontroller devices. these peripheral devices may be serial eeproms, shift registers, display drivers, a/d converters, etc. the spi module is compatible with the spi and siop motorola ? interfaces. all devices of the PIC24FJ128GC010 family include two spi modules. the module supports operation in two buffer modes. in standard buffer mode, data is shifted through a single serial buffer. in enhanced buffer mode, data is shifted through an 8-level fifo buffer. the module also supports a basic framed spi protocol while operating in either master or slave mode. a total of four framed spi configurations are supported. the spi serial interface consists of four pins: ? sdix: serial data input ? sdox: serial data output ? sckx: shift clock input or output ? ssx : active-low slave select or frame synchronization i/o pulse the spi module can be configured to operate using 2, 3 or 4 pins. in the 3-pin mode, ssx is not used; in the 2-pin mode, both sdox and ssx are not used. block diagrams of the module in standard and enhanced modes are shown in figure 16-1 and figure 16-2 . note: this data sheet summarizes the features of this group of pic24f devices. it is not intended to be a comprehensive reference source. for more information, refer to the ?pic24f family reference manual? , ?serial peripheral interface (spi)? (ds39699). the information in this data sheet supersedes the information in the frm. note: do not perform read/modify/write opera- tions (such as bit-oriented instructions) on the spixbuf register in either standard or enhanced buffer mode. note: in this section, the spi modules are referred to together as spix, or separately as spi1 or spi2. special function regis- ters will follow a similar notation. for example, spixcon1 and spixcon2 refer to the control registers for any of the two spi modules.

PIC24FJ128GC010 family ds30009312b-page 270 ? 2012-2013 microchip technology inc. 19.2 usb buffer descriptors and the bdt endpoint buffer control is handled through a structure called the buffer descriptor table (bdt). this provides a flexible method for users to construct and control endpoint buffers of various lengths and configurations. the bdt can be located in any available 512-byte, aligned block of data ram. the bdt pointer (u1bdtp1) contains the upper address byte of the bdt and sets the location of the bdt in ram. the user must set this pointer to indicate the table?s location. the bdt is composed of buffer descriptors (bds) which are used to define and control the actual buffers in the usb ram space. each bd consists of two 16-bit, ?soft? (non-fixed-address) registers, bdnstat and bdnadr, where n represents one of the 64 possible bds (range of 0 to 63). bdnstat is the status register for bdn, while bdnadr specifies the starting address for the buffer associated with bdn. depending on the endpoint buffering configuration used, there are up to 64 sets of buffer descriptors, for a total of 256 bytes. at a minimum, the bdt must be at least 8 bytes long. this is because the ?usb 2.0 otg specification? mandates that every device must have endpoint 0 with both input and output for initial setup. endpoint mapping in the bdt is dependent on three variables: ? endpoint number (0 to 15) ? endpoint direction (rx or tx) ? ping-pong settings (u1cnfg1<1:0>) figure 19-7 illustrates how these variables are used to map endpoints in the bdt. in host mode, only endpoint 0 buffer descriptors are used. all transfers utilize the endpoint 0 buffer descrip- tor and endpoint control register (u1ep0). for received packets, the attached device?s source endpoint is indicated by the value of endpt<3:0> in the usb status register (u1stat<7:4>). for transmitted packets, the attached device?s destination endpoint is indicated by the value written to the token register (u1tok). figure 19-7: bdt mapping for endpoint buffering modes note: since bdnadr is a 16-bit register, only the first 64 kbytes of ram can be accessed by the usb module. ep1 tx even ep1 rx even ep1 rx odd ep1 tx odd descriptor descriptor descriptor descriptor ep1 tx ep15 tx ep1 rx ep0 rx ppb<1:0> = 00 ep0 tx ep1 tx no ping-pong ep15 tx ep0 tx ep0 rx even ppb<1:0> = 01 ep0 rx odd ep1 rx ping-pong buffer ep15 tx odd ep0 tx even ep0 rx even ppb<1:0> = 10 ep0 rx odd ep0 tx odd ping-pong buffers descriptor descriptor descriptor descriptor descriptor descriptor descriptor descriptor descriptor descriptor descriptor descriptor note: memory area is not shown to scale. descriptor descriptor descriptor descriptor buffers on ep0 out on all eps ep1 tx even ep1 rx even ep1 rx odd ep1 tx odd descriptor descriptor descriptor descriptor ep15 tx odd ep0 rx ppb<1:0> = 11 ep0 tx ping-pong buffers descriptor descriptor descriptor on all other eps except ep0 total bdt space: total bdt space: total bdt space: total bdt space: 128 bytes 132 bytes 256 bytes 248 bytes
? 2012-2013 microchip technology inc. ds30009312b-page 271 PIC24FJ128GC010 family bds have a fixed relationship to a particular endpoint, depending on the buffering configuration. tab l e 1 9- 2 provides the mapping of bds to endpoints. this rela- tionship also means that gaps may occur in the bdt if endpoints are not enabled contiguously. this, theoreti- cally, means that the bds for disabled endpoints could be used as buffer space. in practice, users should avoid using such spaces in the bdt unless a method of validating bd addresses is implemented. 19.2.1 buffer ownership because the buffers and their bds are shared between the cpu and the usb module, a simple semaphore mechanism is used to distinguish which is allowed to update the bd and associated buffers in memory. this is done by using the uown bit as a semaphore to distinguish which is allowed to update the bd and associated buffers in memory. uown is the only bit that is shared between the two configurations of bdnstat. when uown is clear, the bd entry is ?owned? by the microcontroller core. when the uown bit is set, the bd entry and the buffer memory are ?owned? by the usb peripheral. the core should not modify the bd or its corresponding data buffer during this time. note that the microcontroller core can still read bdnstat while the sie owns the buffer and vice versa. the buffer descriptors have a different meaning based on the source of the register update. register 19-1 and register 19-2 show the differences in bdnstat depending on its current ?ownership?. when uown is set, the user can no longer depend on the values that were written to the bds. from this point, the usb module updates the bds as necessary, over- writing the original bd values. the bdnstat register is updated by the sie with the token pid and the transfer count is updated. 19.2.2 dma interface the usb otg module uses a dedicated dma to access both the bdt and the endpoint data buffers. since part of the address space of the dma is dedi- cated to the buffer descriptors, a portion of the memory connected to the dma must comprise a contiguous address space, properly mapped for the access by the module. table 19-2: assignment of buffer descriptors for the different buffering modes endpoint bds assigned to endpoint mode 0 (no ping-pong) mode 1 (ping-pong on ep0 out) mode 2 (ping-pong on all eps) mode 3 (ping-pong on all other eps, except ep0) out in out in out in out in 0 0 1 0 (e), 1 (o) 2 0 (e), 1 (o) 2 (e), 3 (o) 0 1 1 2 3 3 4 4 (e), 5 (o) 6 (e), 7 (o) 2 (e), 3 (o) 4 (e), 5 (o) 2 4 5 5 6 8 (e), 9 (o) 10 (e), 11 (o) 6 (e), 7 (o) 8 (e), 9 (o) 3 6 7 7 8 12 (e), 13 (o) 14 (e), 15 (o) 10 (e), 11 (o) 12 (e), 13 (o) 4 8 9 9 10 16 (e), 17 (o) 18 (e), 19 (o) 14 (e), 15 (o) 16 (e), 17 (o) 5 10 11 11 12 20 (e), 21 (o) 22 (e), 23 (o) 18 (e), 19 (o) 20 (e), 21 (o) 6 12 13 13 14 24 (e), 25 (o) 26 (e), 27 (o) 22 (e), 23 (o) 24 (e), 25 (o) 7 14 15 15 16 28 (e), 29 (o) 30 (e), 31 (o) 26 (e), 27 (o) 28 (e), 29 (o) 8 16 17 17 18 32 (e), 33 (o) 34 (e), 35 (o) 30 (e), 31 (o) 32 (e), 33 (o) 9 18 19 19 20 36 (e), 37 (o) 38 (e), 39 (o) 34 (e), 35 (o) 36 (e), 37 (o) 10 20 21 21 22 40 (e), 41 (o) 42 (e), 43 (o) 38 (e), 39 (o) 40 (e), 41 (o) 11 22 23 23 24 44 (e), 45 (o) 46 (e), 47 (o) 42 (e), 43 (o) 44 (e), 45 (o) 12 24 25 25 26 48 (e), 49 (o) 50 (e), 51 (o) 46 (e), 47 (o) 48 (e), 49 (o) 13 26 27 27 28 52 (e), 53 (o) 54 (e), 55 (o) 50 (e), 51 (o) 52 (e), 53 (o) 14 28 29 29 30 56 (e), 57 (o) 58 (e), 59 (o) 54 (e), 55 (o) 56 (e), 57 (o) 15 30 31 31 32 60 (e), 61 (o) 62 (e), 63 (o) 58 (e), 59 (o) 60 (e), 61 (o) legend: (e) = even transaction buffer, (o) = odd transaction buffer

(se0 to j-state). after it occurs, wait 100 ms for the device power to stabilize. 6. check the state of the jstate and se0 bits in u1con. if the jstate bit (u1con<7>) is ? 0 ?, the connecting device is low speed. if the con- necting device is low speed, set the low lspden and lspd bits (u1addr<7> and u1ep0<7>) to enable low-speed operation. 7. reset the usb device by setting the usbrst bit (u1con<4>) for at least 50 ms, sending reset signaling on the bus. after 50 ms, terminate the reset by clearing usbrst. 8. in order to keep the connected device from going into suspend, enable the sof packet generation by setting the sofen bit. 9. wait 10 ms for the device to recover from reset. 10. perform enumeration as described by chapter 9 of the ?usb 2.0 specification? .

? 2012-2013 microchip technology inc. ds30009312b-page 279 PIC24FJ128GC010 family 19.6.2 host negotiation protocol (hnp) in usb otg applications, a dual role device (drd) is a device that is capable of being either a host or a peripheral. any otg drd must support host negotiation protocol (hnp). hnp allows an otg b-device to temporarily become the usb host. the a-device must first enable the b-device to follow hnp. refer to the ?on-the-go supplement? to the ?usb 2.0 specification? for more information regarding hnp. hnp may only be initiated at full speed. after being enabled for hnp by the a-device, the b-device requests being the host any time that the usb link is in suspend state, by simply indicating a discon- nect. this can be done in software by clearing dppulup and dmpulup. when the a-device detects the disconnect condition (via the urstif (u1ir<0>) interrupt), the a-device may allow the b-device to take over as host. the a-device does this by signaling con- nect as a full-speed function. software may accomplish this by setting dppulup. if the a-device responds instead with resume signaling, the a-device remains as host. when the b-device detects the connect condition (via attachif (u1ir<6>), the b-device becomes host. the b-device drives reset signaling prior to using the bus. when the b-device has finished in its role as host, it stops all bus activity and turns on its d+ pull-up resistor by setting dppulup. when the a-device detects a suspend condition (idle for 3 ms), the a-device turns off its d+ pull-up. the a-device may also power down the v bus supply to end the session. when the a-device detects the connect condition (via attachif), the a-device resumes host operation and drives reset signaling. 19.6.3 external v bus comparators the external v bus comparator option is enabled by set- ting the uvcmpdis bit (u1cnfg2<1>). this disables the internal v bus comparators, removing the need to attach v bus to the microcontroller?s v bus pin. the external comparator interface uses either the v cmpst1 and v cmpst2 pins, or the v busvld , sessvld and sessend pins, based upon the setting of the uvcmpsel bit (u1cnfg2<5>). these pins are digital inputs and should be set in the following patterns (see tab l e 1 9- 3 ), based on the current level of the v bus voltage. table 19-3: external v bus comparator states if uvcmpsel = 0 v cmpst1 v cmpst2 bus condition 00 v bus < v b _ sess _ end 10 v b _ sess _ end < v bus < v a _ sess _v ld 01 v a _ sess _v ld < v bus < v a _v bus _v ld 11 v bus > v bus _v ld if uvcmpsel = 1 v busvld sessvld sessend bus condition 00 1 v bus < v b _ sess _ end 00 0 v b _ sess _ end < v bus < v a _ sess _v ld 01 0 v a _ sess _v ld < v bus < v a _v bus _v ld 11 0 v bus > v bus _v ld

? 2012-2013 microchip technology inc. ds30009312b-page 303 PIC24FJ128GC010 family 21.0 enhanced parallel master port (epmp) the enhanced parallel master port (epmp) module pro- vides a parallel, 4-bit (master mode only), 8-bit (master and slave modes) or 16-bit (master mode only) data bus interface to communicate with off-chip modules, such as memories, fifos, lcd controllers and other microcon- trollers. this module can serve as either the master or the slave on the communication bus. for epmp master modes, all external addresses are mapped into the internal extended data space (eds). this is done by allocating a region of the eds for each chip select (cs) and then assigning each chip select to a particular external resource, such as a memory or external controller. this region should not be assigned to another device resource, such as ram or sfrs. to perform a write or read on an external resource, the cpu simply performs a write or read within the address range assigned for the epmp. key features of the epmp module are: ? extended data space (eds) interface allows direct access from the cpu ? up to 23 programmable address lines ? up to 2 chip select lines ? up to 2 acknowledgment lines (one per chip select) ? 4-bit, 8-bit or 16-bit wide data bus ? programmable strobe options (per chip select): - individual read and write strobes; or - read/write strobe with enable strobe ? programmable address/data multiplexing ? programmable address wait states ? programmable data wait states (per chip select) ? programmable polarity on control signals (per chip select) ? legacy parallel slave port (psp) support ? enhanced parallel slave support: - address support - 4-byte deep auto-incrementing buffer 21.1 specific package variations while all PIC24FJ128GC010 family devices implement the epmp, i/o pin constraints place some limits on 16-bit master mode operations in some package types. this is reflected in the number of dedicated chip select pins implemented and the number of dedicated address lines that are available. the differences are summarized in table 21-1 . all available epmp pin functions are summarized in tab l e 2 1- 2 . for 64-pin devices, the dedicated chip select pins (pmcs1 and pmcs2) are not implemented. in addi- tion, only 16 address lines (pma<15:0>) are available. if required, pma14 and pma15 can be remapped to function as pmcs1 and pmcs2, respectively. the memory space addressable by the device depends on the number of address lines available, as well as the number of chip select signals required for the application. devices with lower pin counts are more affected by chip select requirements, as these take away address lines. table 21-1 shows the maximum addressable range for each pin count. table 21-1: epmp feature differences by device pin count note: this data sheet summarizes the features of this group of pic24f devices. it is not intended to be a comprehensive reference source. for more information, refer to the ? pic24f family reference manual ?, ?enhanced parallel master port (epmp)?

PIC24FJ128GC010 family ds30009312b-page 324 ? 2012-2013 microchip technology inc. 23.2 rtcc module registers the rtcc module registers are organized into three categories: ? rtcc control registers ? rtcc value registers ? alarm value registers 23.2.1 register mapping to limit the register interface, the rtcc timer and alarm time registers are accessed through corre- sponding register pointers. the rtcc value register window (rtcvalh and rtcvall) uses the rtcptr<1:0> bits (rcfgcal<9:8>) to select the desired timer register pair (see tab l e 2 3- 1 ). by writing the rtcvalh byte, the rtcc pointer value, the rtcptr<1:0> bits decrement by one until they reach ? 00 ?. once they reach ? 00 ?, the minutes and seconds value will be accessible through rtcvalh and rtcvall until the pointer value is manually changed. table 23-1: rtcval register mapping the alarm value register window (alrmvalh and alrmvall) uses the alrmptr<1:0> bits (alcfgrpt<9:8>) to select the desired alarm register pair (see table 23-2 ). by writing the alrmvalh byte, the alarm pointer value, alrmptr<1:0> bits, decrement by one until they reach ? 00 ?. once they reach ? 00 ?, the alrmmin and alrmsec value will be accessible through alrmvalh and alrmvall until the pointer value is manually changed. table 23-2: alrmval register mapping considering that the 16-bit core does not distinguish between 8-bit and 16-bit read operations, the user must be aware that when reading either the alrmvalh or alrmvall bytes, the alrmptr<1:0> value will be decremented. the same applies to the rtcvalh or rtcvall bytes with the rtcptr<1:0> bits being decremented. 23.2.2 write lock in order to perform a write to any of the rtcc timer registers, the rtcwren bit (rcfgcal<13>) must be set (see example 23-1 ). 23.2.3 selecting rtcc clock source the clock source for the rtcc module can be selected using the rtclk<1:0> bits in the rtcpwc register. when the bits are set to ? 00 ?, the secondary oscillator (sosc) is used as the reference clock and when the bits are ? 01 ?, lprc is used as the reference clock. when rtclk<1:0> = 10 and 11 , the external power line (50 hz and 60 hz) is used as the clock source. example 23-1: setting the rtcwren bit rtcptr<1:0> rtcc value register window rtcval<15:8> rtcval<7:0> 00 minutes seconds 01 weekday hours 10 month day 11 ? year alrmptr <1:0> alarm value register window alrmval<15:8> alrmval<7:0> 00 alrmmin alrmsec 01 alrmwd alrmhr 10 alrmmnth alrmday 11 ?? note: this only applies to read operations and not write operations. note: to avoid accidental writes to the timer, it is recommended that the rtcwren bit (rcfgcal<13>) is kept clear at any other time. for the rtcwren bit to be set, there is only one instruction cycle time window allowed between the 55h/aa sequence and the setting of rtcwren; therefore, it is recommended that code follow the procedure in example 23-1 . asm volatile (?push w7?); asm volatile (?push w8?); asm volatile (?disi #5?); asm volatile (?mov #0x55, w7?); asm volatile (?mov w7, _nvmkey?); asm volatile (?mov #0xaa, w8?); asm volatile (?mov w8, _nvmkey?); asm volatile (?bset _rcfgcal, #13?); //set the rtcwren bit asm volatile (?pop w8?); asm volatile (?pop w7?);

(ideal frequency ? ? measured frequency) * 60 = clocks per minute ? ideal frequency = 32,768 hz note: it is up to the user to include, in the error value, the initial error of the crystal: drift due to temperature and drift due to crystal aging. note: changing any of the registers, other than the rcfgcal and alcfgrpt registers, and the chime bit, while the alarm is enabled (alrmen = 1 ), can result in a false alarm event leading to a false alarm interrupt. to avoid a false alarm event, the timer and alarm values should only be changed while the alarm is disabled (alrmen = 0 ). it is recommended that the alcfgrpt register and chime bit be changed when rtcsync = 0 .

PIC24FJ128GC010 family ds30009312b-page 336 ? 2012-2013 microchip technology inc. 24.1 user interface 24.1.1 polynomial interface the crc module can be programmed for crc polynomials of up to the 32 nd order, using up to 32 bits. polynomial length, which reflects the highest exponent in the equation, is selected by the plen<4:0> bits (crccon2<4:0>). the crcxorl and crcxorh registers control which exponent terms are included in the equation. setting a particular bit includes that exponent term in the equa- tion. functionally, this includes an xor operation on the corresponding bit in the crc engine. clearing the bit disables the xor. for example, consider two crc polynomials, one a 16-bit and the other a 32-bit equation. equation 24-1: 16-bit, 32-bit crc polynomials to program these polynomials into the crc generator, set the register bits, as shown in table 24-1 . note that the appropriate positions are set to ? 1 ? to indi- cate that they are used in the equation (for example, x26 and x23). the ? 0 ? bit required by the equation is always xored; thus, x0 is a don?t care. for a poly- nomial of length 32, it is assumed that the 32 nd bit will be used. therefore, the x<31:1> bits do not have the 32 nd bit. 24.1.2 data interface the module incorporates a fifo that works with a variable data width. input data width can be configured to any value, between 1 and 32 bits, using the dwidth<4:0> bits (crccon2<12:8>). when the data width is greater than 15, the fifo is 4 words deep. when the dwidthx bits are between 15 and 8, the fifo is 8 words deep. when the dwidthx bits are less than 8, the fifo is 16 words deep. the data for which the crc is to be calculated must first be written into the fifo. even if the data width is less than 8, the smallest data element that can be writ- ten into the fifo is 1 byte. for example, if the dwidthx bits are 5, then the size of the data is dwidth<4:0> + 1 or 6. the data is written as a whole byte; the two unused upper bits are ignored by the module. once data is written into the msb of the crcdat reg- isters (that is, the msb as defined by the data width), the value of the vword<4:0> bits (crccon1<12:8>) increments by one. for example, if the dwidthx bits are 24, the vwordx bits will increment when bit 7 of crcdath is written. therefore, crcdatl must always be written to before crcdath. the crc engine starts shifting data when the crcgo bit is set and the value of the vwordx bits is greater than zero. each word is copied out of the fifo into a buffer regis- ter, which decrements the vwordx bits. the data is then shifted out of the buffer. the crc engine contin- ues shifting at a rate of two bits per instruction cycle, until the vwordx bits reach zero. this means that for a given data width, it takes half that number of instruc- tions for each word to complete the calculation. for example, it takes 16 cycles to calculate the crc for a single word of 32-bit data. when the vwordx bits reach the maximum value for the configured value of the dwidthx bits (4, 8 or 16), the crcful bit becomes set. when the vwordx bits reach zero, the crcmpt bit becomes set. the fifo is emptied and the vword<4:0> bits are set to ? 00000 ? whenever crcen is ? 0 ?. at least one instruction cycle must pass after a write to crcwdat before a read of the vwordx bits is done. and x32+x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1 x16 + x12 + x5 + 1 table 24-1: crc setup examples for 16 and 32-bit polynomials crc control bits bit values 16-bit polynomial 32-bit polynomial plen<4:0> 01111 11111 x<31:16> 0000 0000 0000 0001 0000 0100 1100 0001 x<15:0> 0001 0000 0010 000x 0001 1101 1011 011x
? 2012-2013 microchip technology inc. ds30009312b-page 337 PIC24FJ128GC010 family 24.1.3 data shift direction the lendian bit (crccon1<3>) is used to control the shift direction. by default, the crc will shift data through the engine, msb first. setting lendian (= 1 ) causes the crc to shift data, lsb first. this setting allows better integration with various communication schemes and removes the overhead of reversing the bit order in software. note that this only changes the direction the data is shifted into the engine. the result of the crc calculation will still be a normal crc result, not a reverse crc result. 24.1.4 interrupt operation the module generates an interrupt that is configurable by the user for either of two conditions. if crcisel is ? 0 ?, an interrupt is generated when the vword<4:0> bits make a transition from a value of ? 1 ? to ? 0 ?. if crcisel is ? 1 ?, an interrupt will be generated after the crc operation finishes and the module sets the crcgo bit to ? 0 ?. manually setting crcgo to ? 0 ? will not generate an interrupt. note that when an interrupt occurs, the crc calculation would not yet be complete. the module will still need (plenx + 1)/2 clock cycles after the interrupt is generated until the crc calculation is finished. 24.1.5 typical operation to use the module for a typical crc calculation: 1. set the crcen bit to enable the module. 2. configure the module for desired operation: a) program the desired polynomial using the crcxorl and crcxorh registers, and the plen<4:0> bits. b) configure the data width and shift direction using the dwidthx and lendian bits. c) select the desired interrupt mode using the crcisel bit. 3. preload the fifo by writing to the crcdatl and crcdath registers until the crcful bit is set or no data is left. 4. clear old results by writing 00h to crcwdatl and crcwdath. the crcwdat registers can also be left unchanged to resume a previously halted calculation. 5. set the crcgo bit to start calculation. 6. write remaining data into the fifo as space becomes available. 7. when the calculation completes, crcgo is automatically cleared. an interrupt will be generated if crcisel = 1 . 8. read crcwdatl and crcwdath for the result of the calculation. there are eight registers used to control programmable crc operation: ? crccon1 ? crccon2 ? crcxorl ? crcxorh ? crcdatl ? crcdath ? crcwdatl ? crcwdath the crccon1 and crccon2 registers ( register 24-1 and register 24-2 ) control the operation of the module and configure the various settings. the crcxor registers ( register 24-3 and register 24-4 ) select the polynomial terms to be used in the crc equation. the crcdat and crcwdat registers are each register pairs that serve as buffers for the double-word input data, and crc processed output, respectively.

? 2012-2013 microchip technology inc. ds30009312b-page 347 PIC24FJ128GC010 family 26.0 12-bit high-speed, pipeline a/d converter the 12-bit pipeline a/d converter has the following key features: ? conversion speeds of up to 10 msps ? up to 50 analog single-ended input channels or up to 15 unique differential input channel pairs ? 12-bit conversion resolution ? multiple internal reference input channels ? external voltage reference input pins ? automated threshold scan and compare operation to pre-evaluate conversion results ? extended automated and fully programmable sampling sequences from up to four different lists ? conversion result accumulation ? selectable conversion trigger source ? internal 32-word, configurable conversion result buffer ? eight options for results alignment ? configurable interrupt generation ? operation during cpu sleep and idle modes the a/d converter module is a pipelined 12-bit a/d converter, capable of sampling up to once per a/d clock cycle. its operation is enhanced with a wide range of automatic sampling options, tighter integration with other analog modules, result accumulation across many samples and a configurable results buffer. a simplified block diagram for the module is shown in figure 26-1 . 26.1 basic operation to perform a standard a/d conversion: 1. configure the module: a) configure port pins as analog inputs by setting the appropriate bits in the ansx registers (see section 11.2 ?configuring analog port pins (ansx)? for more information). b) configure ?global? adcon1, adcon2 and adcon3 control settings, but do not set the adon bit until all global settings are configured: ? configure a/d clock source/rate ? select a/d reference sources ? configure data formatting ? configure other settings c) enable the a/d module by setting the adon bit (adcon1<15>). d) wait until the adready bit (adstath<1>) becomes set, indicating the module is finished with internal calibration and initialization. e) configure sample list 0 settings, controlled by the adl0conh and adl0conl regis- ters, but do not enable the sample list yet (slen): ? select the desired sample list interrupt generation settings ? select a data write mode (ex: write all results to buffer) ? configure analog sampling time (samc<4:0>) ? select a trigger source ? specify how many entries are in the sample list (slsize<4:0>) ? configure other sample list 0 specific settings f) initialize the adtbl0 register (and higher if slsizex > 0) to select the analog channel(s) to be included in sample list 0. g) configure and enable a/d interrupts (if desired): ? clear the ad1if and sl0if bits ? select an interrupt priority ? enable ad1ie h) enable sample list 0 by setting the slen bit (in adl0conl<15>). i) generate a trigger event for sample list 0 (as configured in step e ). j) wait for the sl0if or top level ad1if inter- rupt flag to assert, indicating that the a/d result(s) are now ready. k) read the respective result(s) from the appro- priate adresn register(s) (as configured based on the buforg setting). note: this data sheet summarizes the features of this group of pic24f devices. it is not intended to be a comprehensive reference source. for more information on the pipe- line a/d converter, refer to the ?pic24f family reference manual? , ?12-bit, high-speed pipeline a/d converter?

PIC24FJ128GC010 family ds30009312b-page 370 ? 2012-2013 microchip technology inc. 27.1 important differences compared to conventional a/ds in principle, the sigma-delta a/d converter does what most other a/ds do: it samples an analog input voltage and generates a digital output code representing the analog voltage. there are, however, a number of differ- ences when comparing a sigma-delta converter to conventional a/d converters, such as the successive approximation register (sar) design that is popular on many of today?s microcontrollers. the most important differences that are noticeable at the application level include: ? readily achieved resolution/quality of result ? analog channel sampling methodology ? uncorrected offset error ? uncorrected gain error 27.1.1 result quality and oversampling in a typical application, involving switching digital circuitry, oscillators, clocks and other noise sources common in a microcontroller-based circuit, it is often difficult to reduce the high-frequency noise floor below some arbitrary value. for a/ds, which perform instan- taneous ?snapshot? based sampling (e.g., charging a sample-and-hold capacitor in a conventional sar-based a/d), this noise floor ultimately restricts the maximum achievable stable result resolution. to achieve higher effective stable resolution and to minimize the effects of high-frequency noise, the sigma-delta a/d converter implements inherent over- sampling in the design. this oversampling has an effect similar to low-pass filtering the analog signal and voltage references to the a/d. therefore, when the converter generates a result, the output code rep- resents the average voltage of the signal or reference being measured over a specific time window, rather than an instantaneous snapshot in time (like that of the sar-based a/d). this sampling method enables the sigma-delta a/d converter to generate stable results at significantly higher resolution than is typically achievable with conventional a/d designs. the design of this sigma-delta a/d converter allows user-configurable oversampling ratios (osrs), between 16 and 1024. the lowest settings provide the fastest results, but they sacrifice result code accuracy. the highest osr settings provide the best quality and most stable results, but generate results at a much slower rate. 27.1.2 uncorrected offset error when uncorrected, the sigma-delta a/d converter typically has more lsbs worth of offset error than conventional sar-based a/ds. this is partly due to the high resolution and small size of each lsb. additionally, internal or external input circuitry, such as the internal input gain stage, can also introduce some offset error. fortunately, the sigma-delta a/d converter imple- ments a feature that allows it to measure its own internal offset error. this feature is controlled by the voscal bit (sd1con1<4>). once the application firmware has measured the internal offset error, the digital output code can be saved in the firmware, and subsequently subtracted from all future a/d measure- ments on the regular input channel(s). this procedure significantly improves the absolute accuracy of the a/d and is recommended for most applications. 27.1.3 uncorrected gain error when uncorrected, sigma-delta a/d converters typi- cally exhibit high gain error compared to other a/d designs. to obtain high absolute accuracy from the sigma-delta a/d converter, it is necessary to compen- sate for both offset error and gain error. gain error can be corrected by first removing the offset error, then multiplying the resulting code with a suitable gain error correction factor. one of the input channel settings, selectable in the sd1con3 register, allows the a/d to measure its own references. when a measurement (with a gain of 1) is performed on this channel, the result code can be cor- rected for offset error (using the method described in section 27.1.2 ?uncorrected offset error? ) and then used to calculate the gain error correction factor. once the gain error correction factor is known, it can be saved and stored in the firmware, so that it may be used later to correct for gain error when performing measurements on the other a/d input channels.

PIC24FJ128GC010 family ds30009312b-page 410 ? 2012-2013 microchip technology inc. 34.3 watchdog timer (wdt) for PIC24FJ128GC010 family devices, the wdt is driven by the lprc oscillator. when the wdt is enabled, the clock source is also enabled. the nominal wdt clock source from lprc is 31 khz. this feeds a prescaler that can be configured for either 5-bit (divide-by-32) or 7-bit (divide-by-128) operation. the prescaler is set by the fwpsa configuration bit. with a 31 khz input, the prescaler yields a nominal wdt time-out period (t wdt ) of 1 ms in 5-bit mode or 4 ms in 7-bit mode. a variable postscaler divides down the wdt prescaler output and allows for a wide range of time-out periods. the postscaler is controlled by the wdtps<3:0> con- figuration bits (cw1<3:0>), which allows the selection of a total of 16 settings, from 1:1 to 1:32,768. using the prescaler and postscaler time-out periods, ranges from 1 ms to 131 seconds can be achieved. the wdt, prescaler and postscaler are reset: ? on any device reset ? on the completion of a clock switch, whether invoked by software (i.e., setting the oswen bit after changing the noscx bits) or by hardware (i.e., fail-safe clock monitor) ? when a pwrsav instruction is executed (i.e., sleep or idle mode is entered) ? when the device exits sleep or idle mode to resume normal operation ?by a clrwdt instruction during normal execution if the wdt is enabled, it will continue to run during sleep or idle modes. when the wdt time-out occurs, the device will wake the device and code execution will continue from where the pwrsav instruction was executed. the corresponding sleep or idle (rcon<3:2>) bit will need to be cleared in software after the device wakes up. the wdt flag bit, wdto (rcon<4>), is not auto- matically cleared following a wdt time-out. to detect subsequent wdt events, the flag must be cleared in software. 34.3.1 windowed operation the watchdog timer has an optional fixed window mode of operation. in this windowed mode, clrwdt instructions can only reset the wdt during the last 1/4 of the programmed wdt period. a clrwdt instruction executed before that window causes a wdt reset, similar to a wdt time-out. windowed wdt mode is enabled by programming the windis configuration bit (cw1<5>) to ? 0 ?. 34.3.2 control register the wdt is enabled or disabled by the fwdten<1:0> configuration bits. when the configuration bits, fwdten<1:0> = 11 , the wdt is always enabled. the wdt can be optionally controlled in software when the configuration bits, fwdten<1:0> = 10 . when fwdten<1:0> = 00 , the watchdog timer is always disabled. the wdt is enabled in software by setting the swdten control bit (rcon<5>). the swdten control bit is cleared on any device reset. the software wdt option allows the user to enable the wdt for critical code segments and disable the wdt during non-critical segments for maximum power savings. figure 34-2: wdt block diagram note: the clrwdt and pwrsav instructions clear the prescaler and postscaler counts when executed. lprc input wdt overflow wake from sleep 31 khz prescaler postscaler fwpsa swdten fwdten<1:0> reset all device resets sleep or idle mode lprc control clrwdt instr. pwrsav instr.

? 2012-2013 microchip technology inc. ds30009312b-page 411 PIC24FJ128GC010 family 34.4 program verification and code protection PIC24FJ128GC010 family devices provide two compli- mentary methods to protect application code from overwrites and erasures. these also help to protect the device from inadvertent configuration changes during run time. 34.4.1 general segment protection for all devices in the PIC24FJ128GC010 family, the on-chip program memory space is treated as a single block, known as the general segment (gs). code pro- tection for this block is controlled by one configuration bit, gcp. this bit inhibits external reads and writes to the program memory space. it has no direct effect in normal execution mode. write protection is controlled by the gwrp bit in the configuration word. when gwrp is programmed to ? 0 ?, internal write and erase operations to program memory are blocked. 34.4.2 code segment protection in addition to global general segment protection, a separate subrange of the program memory space can be individually protected against writes and erases. this area can be used for many purposes where a sep- arate block of write and erase-protected code is needed, such as bootloader applications. unlike common boot block implementations, the specially protected segment in the PIC24FJ128GC010 family devices can be located by the user anywhere in the program space and configured in a wide range of sizes. code segment protection provides an added level of protection to a designated area of program memory by disabling the nvm safety interlock whenever a write or erase address falls within a specified range. it does not override general segment protection controlled by the gcp or gwrp bit. for example, if gcp and gwrp are enabled, enabling segmented code protection for the bottom half of program memory does not undo general segment protection for the top half. the size and type of protection for the segmented code range are configured by the wpfpx, wpend, wpcfg and wpdis bits in configuration word 3. code seg- ment protection is enabled by programming the wpdis bit (= 0 ). the wpfpx bits specify the size of the seg- ment to be protected by specifying the 512-word code page that is the start or end of the protected segment. the specified region is inclusive, therefore, this page will also be protected. the wpend bit determines if the protected segment uses the top or bottom of the program space as a boundary. programming wpend (= 0 ) sets the bottom of program memory (000000h) as the lower boundary of the protected segment. leaving wpend unpro- grammed (= 1 ) protects the specified page through the last page of implemented program memory, including the configuration word locations. a separate bit, wpcfg, is used to protect the last page of program space, including the flash configuration words. programming wpcfg (= 0 ) protects the last page in addition to the pages selected by the wpend and wpfp<6:0> bits? setting. this is useful in circum- stances where write protection is needed for both the code segment in the bottom of the memory and the flash configuration words. the various options for segment code protection are shown in tab l e 3 4- 2 . table 34-2: code segment prot ection configuration options segment configuration bits write/erase protection of code segment wpdis wpend wpcfg 1xx no additional protection is enabled; all program memory protection is configured by gcp and gwrp. 01x addresses from the first address of the code page are defined by wpfp<6:0> through the end of implemented program memory (inclusive); erase/write-protected, including flash configuration words. 001 address, 000000h through the last address of the code page, is defined by wpfp<6:0> (inclusive); write/erase protected. 000 address, 000000h through the last address of code page, is defined by wpfp<6:0> (inclusive); erase/write-protected and the last page, including flash configuration words, are erase/write-protected.
PIC24FJ128GC010 family ds30009312b-page 412 ? 2012-2013 microchip technology inc. 34.4.3 configuration register protection the configuration registers are protected against inadvertent or unwanted changes or reads in two ways. the primary protection method is the same as that of the rp registers ? shadow registers contain a compli- mentary value which is constantly compared with the actual value. to safeguard against unpredictable events, configura- tion bit changes resulting from individual cell level disruptions (such as esd events) will cause a parity error and trigger a device reset. the data for the configuration registers is derived from the flash configuration words in program memory. when the gcp bit is set, the source data for device configuration is also protected as a consequence. even if general segment protection is not enabled, the device configuration can be protected by using the appropriate code segment protection setting. 34.5 jtag interface PIC24FJ128GC010 family devices implement a jtag interface, which supports boundary scan device testing. 34.6 in-circuit serial programming PIC24FJ128GC010 family microcontrollers can be serially programmed while in the end application circuit. this is simply done with two lines for clock (pgecx) and data (pgedx), and three other lines for power (v dd ), ground (v ss ) and mclr . this allows customers to manufacture boards with unprogrammed devices and then program the microcontroller just before shipping the product. this also allows the most recent firmware or a custom firmware to be programmed. 34.7 in-circuit debugger when mplab ? icd 3 is selected as a debugger, the in-circuit debugging functionality is enabled. this func- tion allows simple debugging functions when used with mplab ide. debugging functionality is controlled through the pgecx (emulation/debug clock) and pgedx (emulation/debug data) pins. to use the in-circuit debugger function of the device, the design must implement icsp connections to mclr , v dd , v ss and the pgecx/pgedx pin pair, des- ignated by the icsx configuration bits. in addition, when the feature is enabled, some of the resources are not available for general use. these resources include the first 80 bytes of data ram and two i/o pins.

? 2012-2013 microchip technology inc. ds30009312b-page 417 PIC24FJ128GC010 family 36.0 instruction set summary the pic24f instruction set adds many enhancements to the previous pic ? mcu instruction sets, while main- taining an easy migration from previous pic mcu instruction sets. most instructions are a single program memory word. only three instructions require two program memory locations. each single-word instruction is a 24-bit word divided into an 8-bit opcode, which specifies the instruction type and one or more operands, which further specify the operation of the instruction. the instruction set is highly orthogonal and is grouped into four basic categories: ? word or byte-oriented operations ? bit-oriented operations ? literal operations ? control operations table 36-1 shows the general symbols used in describing the instructions. the pic24f instruction set summary in table 36-2 lists all the instructions, along with the status flags affected by each instruction. most word or byte-oriented w register instructions (including barrel shift instructions) have three operands: ? the first source operand, which is typically a register, ?wb?, without any address modifier ? the second source operand, which is typically a register, ?ws?, with or without an address modifier ? the destination of the result, which is typically a register, ?wd?, with or without an address modifier however, word or byte-oriented file register instructions have two operands: ? the file register specified by the value, ?f? ? the destination, which could either be the file register, ?f?, or the w0 register, which is denoted as ?wreg? most bit-oriented instructions (including simple rotate/shift instructions) have two operands: ? the w register (with or without an address modifier) or file register (specified by the value of ?ws? or ?f?) ? the bit in the w register or file register (specified by a literal value or indirectly by the contents of register, ?wb?) the literal instructions that involve data movement may use some of the following operands: ? a literal value to be loaded into a w register or file register (specified by the value of ?k?) ? the w register or file register where the literal value is to be loaded (specified by ?wb? or ?f?) however, literal instructions that involve arithmetic or logical operations use some of the following operands: ? the first source operand, which is a register, ?wb?, without any address modifier ? the second source operand, which is a literal value ? the destination of the result (only if not the same as the first source operand), which is typically a register, ?wd?, with or without an address modifier the control instructions may use some of the following operands: ? a program memory address ? the mode of the table read and table write instructions all instructions are a single word, except for certain double-word instructions, which were made double-word instructions so that all the required infor- mation is available in these 48 bits. in the second word, the 8 msbs are ? 0 ?s. if this second word is executed as an instruction (by itself), it will execute as a nop . most single-word instructions are executed in a single instruction cycle, unless a conditional test is true or the program counter is changed as a result of the instruc- tion. in these cases, the execution takes two instruction cycles, with the additional instruction cycle(s) executed as a nop . notable exceptions are the bra (uncondi- tional/computed branch), indirect call/goto , all table reads and writes, and return/retfie instructions, which are single-word instructions but take two or three cycles. certain instructions that involve skipping over the sub- sequent instruction require either two or three cycles if the skip is performed, depending on whether the instruction being skipped is a single-word or two-word instruction. moreover, double-word moves require two cycles. the double-word instructions execute in two instruction cycles. note: this chapter is a brief summary of the pic24f instruction set architecture (isa) and is not intended to be a comprehensive reference source.

PIC24FJ128GC010 family devices will typically be able to survive this short-circuit test, but it is recommended to adhere to the absolute maximum specified here to avoid damaging the device. 2: maximum allowable current is a function of device maximum power dissipation (see tab l e 3 7- 1 ). ? notice: stresses above those listed under ?absolute maximum ratings? may cause permanent damage to the device. this is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. exposure to maximum rating conditions for extended periods may affect device reliability.
