SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER Outline of the CPU core
The M32171 Group uses the M32R RISC CPU core, and has an instruction set which is common to all microcomputers in the M32R family. Instructions are processed in five pipelined stages consisting of instruction fetch, decode, execution, memory access, and write back. Thanks to its "out-of-order-completion" mechanism, the M32R CPU allows for clock cycle efficient, instruction execution control. The M32R CPU internally has sixteen 32-bit general-purpose registers. The instruction set consists of 83 discrete instructions, which come in either a 16-bit instruction or a 32-bit instruction format. Use of the 16-bit instruction format helps to reduce the code size of a program. Also, the availability of 32bit instructions facilitates programming and increases the performance at the same clock speed, as compared to architectures with segmented address spaces.
Address space
The M32171 Group's logical addresses are always handled in 32 bits, providing 4 Gbytes of linear address space. The M32171 Group's address space consists of the following.
User space
A 2-Gbyte area from H'0000 0000 to H'7FFF FFFF is the user space. Located in this space are the user ROM area, external extended area, internal RAM area, and SFR (Special Function Register) area (internal peripheral I/O registers). Of these, the user ROM area and external extended area are located differently depending on mode settings.
Boot program space
A 1-Gbyte area from H'8000 0000 to H'BFFF FFFF is the boot program area. This space contains the on-board programming program (boot program) used in blank state by the internal flash memory.
Sum-of-products instructions comparable to DSP
The M32R CPU contains a multiplier/accumulator that can execute 32 bits x 16 bits in one cycle. Therefore, it executes a 32 bit x 32 bit integer multiplication instruction in three cycles. Also, the M32R CPU supports the following four sum-of-products instructions (or multiplication instructions) for DSP function use. (1) 16 high-order register bits x 16 high-order register bits (2) 16 low-order register bits x 16 low-order register bits (3) All 32 register bits x 16 high-order register bits (4) All 32 register bits x 16 low-order register bits Furthermore, the M32R CPU has instructions for rounding the value stored in the accumulator to 16 or 32 bits, and instructions for shifting the accumulator value to adjust digits before storing in a register. Because these instructions also can be executed in one cycle, DSP comparable data processing capability can be obtained by using them in combination with high-speed data transfer instructions such as Load & Address Update or Store & Address Update.
System space
A 1-Gbyte area from H'C000 0000 to H'FFFF FFFF is the system area. This space is reserved for use by development tools such as an in-circuit emulator and debug monitor, and cannot be used by the user.
Three operation modes
The M32170 and M32174 Group has three operation modes: single-chip mode, external extended mode, and processor mode. These operation modes are changed from one to another by setting the MOD0 and MOD1 pins.

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER Built-in Flash Memory and RAM
The M32171F4VFP contains 512-Kbyte flash memory and 16-Kbyte RAM. The M32171F3VFP contains 384-Kbyte flash memory and 16-Kbyte RAM. The M32171F2VFP contains 256-Kbyte flash memory and 16-Kbyte RAM. The internal flash memory can be programmed on-board (i.e., while being mounted on the printed circuit board). This means that the same chip as will be used in mass-production can be used directly from the development stage on, allowing for system development without having to change the printed circuit board when proceeding from trial production to mass-production.
Built-in Virtual-Flash Emulation Function
Internal flash memory, which is divided from the first address in units of 8 Kbyte (L banks), can be replaced in 8 -Kbyte blocks (H70080 4000-H'0080 5FFF) from the beginning of the internal RAM. And also the internal flash memory, which is divided from the first address in units of 4-Kbyte area (All S banks), can be replaced within two 4 Kbytes areas (H'0080 6000-H'0080 7FFF). This function allows parts of the program which are frequently changed during development to be altered or evaluated without having to reset the microcomputer each time. What's more, when combined with the realtime debugger, this function helps to reduce the program evaluation period, because data in the RAM can be rewritten without requiring any CPU load.

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER Input/output Ports
The microcomputer has a total of 97 input/output ports P0-P22. (However, P5 is reserved for future use, P14, P16, and P18-P21 do not exist.) The input/output ports can be used as input ports or output ports by setting uptheir direction registers. Each input/output port is a dual-function pin shared with otherinternal peripheral I/O or external extended bus signal lines. These pin functions are selected by using the chip operation mode select or the input/output port operation mode registers. These input/output ports are interfaced using a dedicated power supply to allow for connections to the peripheral circuits operating with 5V or 3.3V.

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER Built-in 10-Channel DMAC
The microcomputer contains 10 channels of DMAC, allowing for data transfer between internal peripheral I/Os, between internal RAM and internal peripheral I/O, and between internal RAMs. DMA transfer requests can be issued from the user-cre ated software, as well as can be triggered by a signal generated by the internal peripheral I/O (A-D converter, MJT, or serial I/O). The microcomputer also supports cascaded connection between DMA channels (starting DMA transfer on a channel at end of transfer on another channel). This makes advanced transfer processing possible without causing any additional CPU load.

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER Built-in 37-Channel Multijunction Timers (MJT)
The microcomputer contains a total of 37 channels of multijunction timers consisting of 11 channels of 16-bit output related timers, 10 channels of 16-bit input/output related timers, eight channels of 16-bit input related timers, eight channels of 32-bit input related timers, Each timer has multiple operation modes to choose from, depending on the purposes of use. Also, the maltijunction timers internally have a clock bus, input event bus, and an output event bus, so that multiple timers can be used in combination allowing for a flexible timer configuration. The output related timers have a correcting function that allows the timer's count value to be incremented or decremented as necessary while count is in progress, making real time output control possible.

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER Built-in Two Independent A-D Converters
The microcomputer contains two 16-channel converters with 10-bit resolution (A-D0 converter and A-D1 converter). In addition to single conversion on each channel, continuous A-D conversion on a combined group of 4, 8, and 16 channels is possible. The A-D converted value can be read out in either 10 bits or 8 bits. In addition to ordinary A-D conversion, the converters support comparator mode in which the set value and A-D converted value are compared to determine which is larger or smaller than the other. When A-D conversion is finished, the converters can generated a DMA transfer request, as well as an interrupt. The A-D converters are interfaced using a dedicated power supply to allow for connections to the peripheral circuits operating with 5V or 3.3V. Table 13 Outline of the A-D Converters

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER 3-channel High-speed Serial I/Os
The microcomputer contains three channels of serial I/Os consisting of two channels that can be set for CSIO mode (clock-synchronized serial I/O) or UART mode (asynchronous serial I/O) and one other channel that can only be set for UART mode. The SIO has the function to generate a DMA transfer request when data reception is completed or the transmit register becomes empty, and is capable of high-speed serial communication without causing any additional CPU load. Table 14 Outline of Serial I/O
Item Number of channels Content CSIO/UART: 2 channels (SIO0,SIO1) UART only : 1 channels (SIO2) Clock During CSIO mode : Internal clock / external clock, selectable (Note1) During UART mode : Internal clock only Transfer mode BRG count sourcef Data format Transmit half-duplex, receive half-duplex, transmit/receive full-duplex (BCLK), f(BCLK)/8, f(BCLK)/32, f(BCLK)/256 (When internal clock is selected) (Note2) CSIO mode : Data length = Fixed to 8 bits Order of transfer = Fixed to LSB first UARTmode : Start bit = 1 bit Character length = 7, 8, or 9 bits Parity bit = Added or not added (When added, selectable between odd and even parity) Stop bit = 1 or 2 bits Order of transfer = Fixed to LSB first Baud rate CSIO mode : UARTmode : Error detection CSIO mode : UARTmode : 152 bits per second to 2 Mbits per second (when operating with f(BCLK) = 20 MHz) 19 bits per second to 156 Kbits per second (when operating with f(BCLK) = 20 MHz) Overrun error only Overrun, parity, and framing errors (The error-sum bit indicates which error has occurred) Fixed cycle clock output function When using SIO0 and SIO1 as UART, this function outputs a divided-by-2 BRG clock from the SCLK pin.
Note 1: During CSIO mode, the maximum input frequency of an external clock is f(BCLK) divided by 16. Note 2: When f(BCLK) is selected for the BRG count source, the BRG set value is subject to limitations.

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER 8-level Interrupt Controller
The Interrupt Controller controls interrupt requests from each internal peripheral I/O (31 sources) by using eight priority levels assigned to each interrupt source, including interrupts disabled. In addition to these interrupts, it handles System Break Interrupt (SBI), Reserved Instruction Exception (RIE), and Address Exception (AE) as nonmaskable interrupts.
Realtime Debugger (RTD)
The Realtime Debugger (RTD) provides a function for accessing directly from the outside to the internal RAM. It uses a dedicated clock-synchronized serial I/O to communicate with the outside. Use of the RTD communicating via dedicated serial lines allows the internal RAM to be read out and rewritten without having to halt the CPU.
Wait Controller
The Wait Controller supports access to external devices. For access to an external extended area of up to 1 Mbytes (during external extended or processor mode), the Wait Controller controls bus cycle extension by inserting one to ____ four wait cycles or using external WAIT signal input.
