r01uh0198ej0500 rev. 5.00 page iii of lviii mar 18, 2011 general precautions in the handling of mpu/mcu products the following usage notes are applicable to all mpu/mcu products from renesas. for detailed usage notes on the products covered by this manual, refer to the relevant sections of the manual. if the descriptions under general precautions in the handling of mpu/mcu products and in the body of the manual differ from each other, the description in the body of the manual takes precedence. 1. handling of unused pins handle unused pins in accord with the directions given under handling of unused pins in the manual. ? the input pins of cmos products are generally in the high-impedance state. in operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of lsi, an associated shoot-through current flows internally, and malfunctions may occur due to the false recognition of the pin state as an input signal. unused pins should be handled as described under handling of unused pins in the manual. 2. processing at power-on the state of the product is undefined at the moment when power is supplied. ? the states of internal circuits in the lsi are indeterminate and the states of register settings and pins are undefined at the moment when power is supplied. in a finished product where the reset signal is applied to the external reset pin, the states of pins are not guaranteed from the moment when power is supplied until the reset process is completed. in a similar way, the states of pins in a product that is reset by an on-chip power-on reset function are not guaranteed from the moment when power is supplied until the power reaches the level at which resetting has been specified. 3. prohibition of access to reserved addresses access to reserved addresses is prohibited. ? the reserved addresses are provided for the possible future expansion of functions. do not access these addresses; the correct operation of lsi is not guaranteed if they are accessed. 4. clock signals after applying a reset, only release the reset line after the operating clock signal has become stable. when switching the clock signal during program execution, wait until the target clock signal has stabilized. ? when the clock signal is generated with an external resonator (or from an external oscillator) during a reset, ensure that the reset line is only released after full stabilization of the clock signal. moreover, when switching to a clock signal produced with an external resonator (or by an external oscillator) while program execution is in progress, wait until the target clock signal is stable. 5. differences between products before changing from one product to another, i.e. to one with a different type number, confirm that the change will not lead to problems. ? the characteristics of mpu/mcu in the same group but having different type numbers may differ because of the differences in internal memory capacity and layout pattern. when changing to products of different type numbers, implement a system-evaluation test for each of the products.

section 1 overview r01uh0198ej0500 rev. 5.00 page 1 of 1560 mar 18, 2011 sh7080 group section 1 overview 1.1 features of sh7083, sh7084, sh7085, and sh7086 this lsi is a single-chip risc (reduced instruction set computer) microcomputer that integrates a renesas original risc cpu core with peripheral functions required for system configuration. the cpu in this lsi has a risc-type instruction set. most instructions can be executed in one state (one system clock cycle), which greatly im proves instruction execu tion speed. in addition, the 32-bit internal-bus architecture enhances data processing power. with this cpu, it has become possible to assemble low-cost, high-performance, and high-functioning systems, even for applications that were previously impossible w ith microcomputers, such as real-time control, which demands high speeds. in addition, this lsi includes on-chip peripheral functions necessary for system configuration, such as large-capacity rom and ram, a dir ect memory access controller (dmac), a data transfer controller (dtc), timers, a serial co mmunication interface (sci), a serial communication interface with fifo (scif), a synchronous serial communication unit (ssu), an a/d converter, an interrupt controller (intc), i/o ports, and an i 2 c bus interface 2 (i 2 c2). this lsi also provides an external memory access support function to enable direct connection to various memory devices or peripheral lsis. these on-chip functions significantly reduces costs of designing and manufacturing application systems. in terms of on-chip rom, f-ztat tm (flexible zero turn around time)* version incorporating flash memory and mask rom version are available. the flash memory can be programmed with a programmer that supports programming of this lsi, and can also be programmed and erased by software. this enables lsi chip to be re-programmed at a user-site while mounted on a board. the features of this lsi are listed in table 1.1. note: * f-ztat tm is a trademark of renesas electronics corp.

(keep at low level for at least the lo ngest bus cycle). see appendix a, pin states, for the status of individual pins during manual reset mode. in the manual reset status, manual reset exception processing starts when the mres pin is first kept low for a set period of time and then returned to high. the cpu will then operate in the same procedures as described for power-on resets.

section 9 bus state controller (bsc) page 358 of 1560 r01uh0198ej0500 rev. 5.00 mar 18, 2011 sh7080 group a. insert one idle cycle to access the interface other than the sdram interface after the write access cycle is performed in the sdram interface. b. insert one idle cycle to access the sdra m interface after the nor mal space interface with the external wait invalidated or the byte-selection sram in terface with the bas bit = 0 specified is accessed. c. insert one idle cycle to access the sd ram interface after the mpx-i/o interface is accessed. d. insert two idle cycles to access the mpx-i/o interface from the external bus that is in the idle status. e. insert one idle cycle to access the mpx-i/o in terface after a read cycle is performed in the normal space interface, byte-selection sram interface with the ba s bit = 0, and the sdram interface. f. insert two idle cycles to access the mpx-i/o interface after a write cycle is performed in the sdram interface. tables 9.29 to 9.34 list the minimum number of id le cycles to be inserted for the normal space interface and the sdram interface. the csnbcr idle setting column in the tables describes the number of idle cycles to be set for iww, iwrwd, iwrws, iwrrd, and iwrrs.

section 9 bus state controller (bsc) r01uh0198ej0500 rev. 5.00 page 375 of 1560 mar 18, 2011 sh7080 group the bus release sequence is as follows. the address bus and data bus are placed in a high- impedance state synchronized with the rising edge of ck. the bus mastership acknowledge signal is asserted 0.5 cycles after the above high impeda nce state, synchronized with the falling edge of ck. the bus control signals such as csn are placed in the high-impedance state at subsequent rising edges of ck. these bus control signals go high one cycle before being placed in the high- impedance state. bus request signals are sampled at the falling edge of ck. by setting the hizcnt bit in cmnr, the cke, rasu , rasl , casu , and casl can be continued to be driven even after the bus is released using the va lues immediately befo re the bus release. the sequence for reclaiming the bus mastership fr om an external device is described below. at 1.5 cycles after the negation of breq is detected at the falling edge of ck, the bus control signals are driven high. the bus acknowledge signa l is negated at the next falling edge of the clock. the fastest timing at which actual bus cycles can be resumed after bus control signal assertion is at the rising edge of the ck where address and data signals are driven. figure 9.51 shows the bus arbitration timing in master mode. in an original external device designed by the user, multiple bus accesses may be generated continuously to reduce the overhead caused by bus arbitration. in this case, to execute sdram refresh correctly, the external device must be de signed to release the bus mastership within the refresh interval time. this lsi has the irqout pin to request the bus while waiting for refresh execution. this lsi continues to assert irqout (low level) until the bus is acquired. when the external device receives this signal and releases the bus, th e lsi acquires the bus and executes refresh. after breq assertion (low level; bus request), the breq signal should be negated (high level; bus release) only after the back is asserted (low level; bus acknowledge). if breq is negated before back is asserted, back may be asserted only for one cycle depending on the breq negation timing, and a bus conflict may occur between the external device and this lsi. ck other bus control signals breq back a29 to a0 d31 to d0 csn figure 9.51 bus arbitration timing

(2) access in view of lsi internal bus master there are three types of lsi internal buses: l bus, i bus, and peripheral bus. the cpu is connected to the l bus. the dmac, dtc, and bus state controller are connected to the i bus. low-speed peripheral modules are connected to the peripheral bus. on-chip memories are connected bidirectionally to the l bus and i bus. for an access of an external space or an on-chip peripheral module, the access is initiated via the i bus. thus, the dmac and dtc can be activated without bus arbitration with the cpu while the cpu is accessing an on-chip memory. since the bus state controller (bsc) incorporates a one-stage write buffer, the bsc can execute an access via the i bus before the previous external bu s cycle is completed in a write cycle. if the on- chip peripheral module is read or written after the external low-speed memory is written, the on- chip peripheral module can be accessed before th e completion of the exte rnal low-speed memory write cycle. in read cycles, the cpu is placed in the wait state until read operation has been completed. to continue the process after the data write to the device has been completed, perform a dummy read to the same address to check for completion of the write before the next process to be executed.

(1) auto-request mode when there is no transfer request signal from an external source, as in a memory-to-memory transfer or a transfer between memory and an on-chip peripheral module unable to request a transfer, auto-request mode allows the dmac to automatically generate a transfer request signal internally. when the de bits in chcr0 to chcr3 and the dme bit in dmaor are set to 1, the transfer begins so long as the ae and nmif bits in dmaor and the te bits in chcr0 to chcr3 are all 0.

(1) fixed mode in this mode, the priority levels among the channels remain fixed. there are two kinds of fixed modes as follows: ? ch0 > ch1 > ch2 > ch3 ? ch0 > ch2 > ch3 > ch1 these are selected by the pr1 and the pr0 bits in dmaor. (2) round-robin mode in round-robin mode each time data of one transfer unit (word, byte, longword, or 16-byte unit) is transferred on one channel, the priority is rotated. the channel on which the transfer was just finished rotates to the bottom of the priority. the round-robin mode operation is shown in figure 10.3. the priority of round-robin mode is ch0 > ch1 > ch2 > ch3 immediately after reset. when round-robin mode is specified, do not mix the cycle steal mode and the burst mode in multiple channels' bus modes.

(the wdt does not run when resets are used for revoking, so keep the res pin low until the clock stabilizes.) 1. before transition to software standby mode, always clear the tme bit in wtcsr to 0. when the tme bit is 1, an erroneous reset or interval timer interrupt may be generated when the count overflows. 2. set the type of count clock used in the cks2 to cks0 bits in wtcsr and the initial values for the counter in the wtcnt counter. these va lues should ensure that the time till count overflow is longer than the clock oscillation settling time. 3. transition to software standby mode by ex ecuting a sleep instruction to stop the clock. 4. the wdt starts counting by detecting a change in the level input to the nmi or irq pin. 5. when the wdt count overflows, the cpg starts supplying the clock and the lsi resumes operation. the wovf flag in wtcsr is not set when this happens. 14.4.2 using watchdog timer mode while operating in watchdog timer mode, the wdt generates an internal reset of the type specified by the rsts bit in wtcsr and asserts a signal through the wdtovf pin every time the counter overflows. 1. set the wt/it bit in wtcsr to 1, set the reset type in the rsts bit, set the type of count clock in the cks2 to cks0 bits, and set th e initial value of the counter in the wtcnt counter. 2. set the tme bit in wtcsr to 1 to start the count in watchdog timer mode. 3. while operating in watchdog timer mode, rewrite the counter periodically to prevent the counter from overflowing. 4. when the counter overflows, the wdt sets the wovf flag in wtcsr to 1, asserts a signal through the wdtovf pin for one cycle of the count clock specified by the cks2 to cks0 bits, and generates a reset of the type specified by the rsts bit. the counter then resumes counting.

(1) asynchronous mode ? data length is selectable: 7 or 8 bits. ? parity bit is selectable. so is the stop bit length (1 or 2 bits). the combination of the preceding selections constitutes the communication format and character length. ? in receiving, it is possible to detect framing er rors, parity errors, overrun errors, and breaks. ? an internal or external clock can be selected as the sci clock source. ? when an internal clock is selected, the sci operates using the clock supplied by the on- chip baud rate generator and can output a clock with a frequency 16 times the bit rate. ? when an external clock is sel ected, the external clock input must have a frequency 16 times the bit rate. (the on-chip baud rate generator is not used.) (2) clock synchronous mode ? the transmission/reception format has a fixed 8-bit data length. ? in receiving, it is possible to detect overrun errors. ? an internal or external clock can be selected as the sci clock source. ? when an internal clock is selected, the sci operates using the on-chip baud rate generator, and outputs a serial clock signal to external devices. ? when an external clock is selected, the sci operates on the input serial clock. the on-chip baud rate generator is not used.

(3) transmitting and receiving data sci initialization (asynchronous mode): before transmitting or receiving, clear the te and re bits to 0 in the serial control register (scscr), then initialize the sci as follows. when changing the operation mode or the communi cation format, always clear the te and re bits to 0 before following the procedure given below. clearing the te bit to 0 sets the tdre flag to 1 and initializes the transmit shift register (sctsr). clearing the re bit to 0, however, does not initialize the rdrf, per, fer, and orer flags or receive data register (scrdr), which retain their previous contents. when an external clock is used, the clock should not be stopped during initia lization or subsequent operation. sci operation becomes unreliable if the clock is stopped.

(a format in which neither parity nor multiprocessor bit is output can also be selected.) d. stop bit(s): one or two 1 bits (stop bits) are output. e. mark state: 1 is output continuously until the start bit that starts the next transmission is sent. 3. the sci checks the tdre flag at the timing for sending the stop bit. if the tdre flag is 0, the data is transferred from sctdr to sctsr, the stop bit is sent, and then serial transmission of the next frame is started. if the tdre flag is 1, the tend flag in scssr is set to 1, the stop bit is sent, and then the "mark state" is entered in which 1 is output. if the teie bit in scscr is set to 1 at this time, a tei interrupt request is generated.

(1) communication format the data length is fixed at eight bits. no parity bit can be added. (2) clock an internal clock generated by the on-chip baud rate generator or an external clock input from the sck pin can be selected as the sci transmit/receive clock. for selection of the sci clock source, see table 15.14. when the sci operates on an internal clock, it outputs the clock signal at the sck pin. eight clock pulses are output per transmitted or received character. when the sci does not perform transmission or reception, the clock signal remain s in the high state. when only reception is performed, output of the synchronous clock continues until an overrun error occurs or the re bit is cleared to 0. for the reception of n characters, select the external clock as the clock source. if the internal clock has to be used, set re and te to 1, then transmit n characters of dummy data at the same time as receiving the n characters of data. (3) transmitting and receiving data sci initialization (clock synchronous mode): before transmitting, receiving, or changing the mode or communication format, the software must clear the te and re bits to 0 in the serial control register (scscr), then initialize the sci. clearing te to 0 sets the tdre flag to 1 and initializes the transmit shift register (sctsr). clearing re to 0, however, does not initialize the rdrf, per, fer, and orer flags and receive data register (scrdr), which retain their previous contents.

[3] serial reception continuation procedure: to continue serial reception, read the receive data register (scrdr) and clear the rdrf flag to 0 before the msb (bit 7) of the current frame is received. the rdrf flag is cleared automatically when the direct memory access controller (dmac) or data transfer controller (dtc) is activated by a receive-data-full interrupt (rxi) request to read the scrdr value, and this step is not needed. figure 15.12 sample flowchart for receivi ng serial data (1)

[2] sci status check and transmit data write: read scssr and check that the tdre flag is set to 1, then write transmit data to sctdr. set the mpbt bit in scssr to 0 or 1. finally, clear the tdre flag to 0. to transmit an id after the sci is initialized, write the id to sctdr. the data is immediately transferred to sctsr and the tdre flag is set to 1. at this point the id has not yet been transmitted from the txd pin, so it is necessary to maintain the mpbt value at 1. clear the mpbt bit to 0 after the next data to be transmitted is written to sctdr and the tdre flag is set to 1. [3] serial transmission continuation procedure: to continue serial transmission, be sure to read 1 from the tdre flag to confirm that writing is possible, then write data to sctdr, and then clear the tdre flag to 0. checking and clearing of the tdre flag is automatic when the dmac or dtc is activated by a transmit data empty interrupt (txi) request, and data is written to sctdr.

section 16 serial communication interface with fifo (scif) r01uh0198ej0500 rev. 5.00 page 847 of 1560 mar 18, 2011 sh7080 group in clock synchronous serial communication, each data bit is output on the communication line from one falling edge of the serial clock to the next. data is guaranteed valid at the rising edge of the serial clock. in each character, the serial data bits are transmitted in order from the lsb (first) to the msb (last). after output of the msb, the communication line remains in the state of the msb. in clock synchronous mode, the scif receives data in synchronization with the rising edge of the serial clock. (1) communication format the data length is fixed at eight bits. no parity bit can be added. (2) clock an internal clock generated by the on-chip baud rate generator or an external clock input from the sck pin can be selected as th e scif transmit/receive clock. when the scif operates on an internal clock, it outputs the clock signal at the sck pin. eight clock pulses are output per transmitted or received character. when the scif is not transmitting or receiving, the clock signal remains in the high st ate. when only receiving, the clock signal outputs while the re bit of scscr is 1 and the number of data in receive fifo is more than the receive fifo data trigger number. in this case, 8 (16 + 1) = 136 pulses of synchronous clock are output. to perform reception of n characters of data, select an external clock as the clock source. if an internal clock should be used, set re = 1 and te = 1 and receive n characters of data simultaneously with the transmission of n characters of dummy data. (3) transmitting and receiving data scif initialization (clock synchronous mode): before transmitting, receiving, or changing the mode or communication format, the software must clear the te and re bits to 0 in the serial control register (scscr), then initialize the scif. clearing te to 0 initializes the transmit shift register (sctsr). clearing re to 0, however, does not initialize the rdf, per, fer, and orer flags and receive data regi ster (scrdr), which retain their previous contents.

section 23 flash memory page 1232 of 1560 r01uh0198ej0500 rev. 5.00 mar 18, 2011 sh7080 group (2) download of on-chip program the on-chip program is automatically downloaded by clearing vbr of the cpu to h'84000000 and then setting the sco bit in the flas h code control and stat us register (fccs) and the flash key code register (fkey), which are programming/erasing interface registers. the user mat is replaced to the embedded pr ogram storage area when downloading. since the flash memory cannot be read when programming/erasing, the procedure program, which is working from download to completion of programming/erasing, must be executed in a space other than the flash memory to be progr ammed/erased (for example, on-chip ram). since the result of download is returned to the programming/erasing interface parameters, whether the normal download is ex ecuted or not can be confirmed. note that vbr can be changed after download is completed. (3) initialization of programming/erasing the operating frequency and user branch are set before execution of programming/erasing. the user branch destination must be in an area other than the user mat area which is in the middle of programming and the area where the on-chip program is downloaded. these settings are performed by using the programmi ng/erasing interface parameters. (4) programming/erasing execution to program or erase, the fwe pin must be brought high and user program mode must be entered. the program data/programming destination address is specified in 128-byte units when programming. the block to be erased is specified in erase-block units when erasing. these specifications are set by using the prog ramming/erasing interface parameters and the on- chip program is initiated. the on-chip program is executed by using the jsr or bsr instruction to perform the subroutine call of th e specified address in the on-chip ram. the execution result is returned to the pr ogramming/erasing interface parameters. the area to be programmed must be erased in advance when programming flash memory. there are limitations and notes on the interrupt processing during programming/erasing. for details, see section 23.8.2, interrupts during programming/erasing. (5) when programming/erasing is executed consecutively when the processing is not ended by the 128-byte programming or one-block erasure, the program address/data and erase-block number must be updated and consecutive programming/erasing is required. since the downloaded on-chip program is left in the on-chip ram after the processing, download and initialization are not required when the same processing is executed consecutively.

(switching to the user boot mat disables programming and erasing. programming of the user boot mat must take place in boot mode or programmer mode.) 1. mat switching by fmats should always be executed from the on-chip ram. the sh microcomputer prefetches execution instructions. therefore, a switchover during program execution in the user mat causes an instruction c ode in the user mat to be prefetched or an instruction in the newly selected user boot mat to be prefetched, thus resulting in unstable operation. 2. to ensure that the mat that has been switche d to is accessible, execute four nop instructions in on-chip ram immediately after writing to fm ats of on-chip ram (this prevents access to the flash memory during mat switching). 3. if an interrupt occurs during switching, there is no guarantee of which memory mat is being accessed. always mask the maskable interrupts before switching mats. in addition, configuring the system so that nmi interrupts do not occur during mat switching is recommended. 4. after the mats have been switched, take care because the interrupt vector table will also have been switched. if the same interrupt processings are to be executed before and after mat switching or interrupt requests cannot be disabled, transfer the interrupt processing routine to on-chip ram, and use the vbr setting to place the interrupt vector table in on chip ram. in this case, make sure the vbr setting change does not conflict with the interrupt occurrence. 5. memory sizes of the user mat and user boot mat are different. when accessing the user boot mat, do not access addresses exceedi ng the 12-kbyte memory space. if access goes beyond the 12-kbyte space, the values read are undefined.

(1) canceling with interrupt the wdt can be used for hot starts. when an nmi or irq interrupt (edge detection) is detected, the clock will be supplied to the entire lsi and so ftware standby mode will be canceled after the time set in the timer control/status register of the wdt has elapsed. interrupt exception handling is then executed. when the priority level of an irq interrupt is lower than the interrupt mask level set in the status register (sr) of the cpu, an interrupt request is not accepted preventing software standby mode from being canceled. when falling-edge detection is selected for the nmi pin, drive the nmi pin high before making a transition to software standby mode. when rising-edge detection is selected for the nmi pin, drive the nmi pin low before making a transition to software standby mode. similarly, when falling-edge detection is selected for the irq pin, drive the irq pin high before making a transition to software standby mode. when rising-edge detection is selected for the irq pin, drive the irq pin low before making a transition to software standby mode. (2) canceling with power-on reset software standby mode is canceled by a power-on reset with the res pin. keep the res pin low until the clock oscillation settles. (3) canceling with manual reset software standby mode is canceled by a manual reset with the mres pin. keep the mres pin low until the clock oscillation settles.
