Description
37-channel multijunction timers (MJT)
32176 Group is a 32-bit, single-chip RISC microcomputer
with built-in flash memory, which was developed for use in
general industrial and household equipment.
To make full use of microcomputer built-in mass volume
flash memory, this microcomputer contains a variety of peripheral functions ranging from two independent blocks of
16-channel A-D converters to 37-channel multifunction timers, 10-channel DMAs, 4-channel serial I/Os, and 1-channel
real-time debugger. Also included 2-channel Full-CAN modules and JTAG (boundary scan facility).
With lower power consumption and low noise characteris
tics also considered, these microcomputers are ideal for embedded equipment applications.
Multifunction timers are incorporated that support various
purposes of use.

Outline of the CPU core
Address space
The M32176 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 contains sixteen 32-bit generalpurpose registers. The instruction set consists of 83 discrete
instructions, which come in either 16-bit or 32-bit instruction
format. Use of the 16-bit instruction format helps to reduce
the program code size. Also, the availability of 32-bit instructions facilitates programming and increases the performance at the same clock speed, as compared to architectures with segmented address spaces.
The 32176 Group’s logical address is always handled in
width of 32-bit, providing a linear address space of up to 4G
bytes. The 32176’s address space is divided into the following spaces.
Multiply-Accumulate instructions comparable to
DSP
User space
A 2G-byte 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.
System space
A 2G-byte area from H’8000 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.
The M32R CPU contains a multiplier/accumulator that can
execute 32-bit × 16-bit in one cycle. Therefore, it executes a
32-bit × 32-bit integer multiplication instruction in three cycles.
Also, the M32R CPU supports the following four multiplyAccumulate instructions (or multiplication instructions) for
DSP function use.
(1) 16 high-order register bits × 16 high-order register bits
(2) 16 low-order register bits × 16 low-order register bits
(3) All 32 register bits × 16 high-order register bits
(4) All 32 register bits × 16 low-order register bits
Furthermore, the M32R CPU has instructions for rounding
the value stored in the accumulator to 16 or 32-bit, 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.
Three operation modes
The M32176 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.

Built-in flash memory and RAM
Built-in Virtual-Flash Emulation Function
The M32176F4VFP/M32176F4TFP contains 512K bytes
flash memory and 24K bytes RAM, the M32176F3VFP/
M32176F3TFP contains 384K bytes flash memory and 24K
bytes RAM, the M32176F2VFP/ M32176F2TFP contains
256K bytes flash memory and 24K bytes RAM.
The internal flash memory can be programmed while being
mounted on the printed circuit board (on-board programming). Use of flash memory allows the same chip as those
used in mass production to be used beginning with the development stage. This means that system development can
be proceeded without having to change the printed circuit
boards during the entire course, from prototype to mass production.
Internal flash memory, which is divided from the first address in
units of 8K bytes (L banks), can be replaced in 8K bytes blocks
(H’0080 4000-H’0080 5FFF, H’0080 8000-H’0080 9FFF) from
the beginning of the internal RAM. And also the internal flash
memory, which is divided from the first address in units of 4K
bytes area (All S banks), can be replaced within two 4K bytes
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
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-created
software, as well as can be triggered by a signal generated by
the internal peripheral I/O (A-D converter, timer, 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.

Also, the multijunction 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.
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, 8 channels of 16-bit input related timers, 8 channels
of 32-bit input related timers. Each timer has multiple operation modes to choose from, depending on the purposes of
use.

16-channel A-D Converters
Moreover, there is also Sample & hold function, input voltage is sampled, when A-D conversion is started, and the AD conversion of the sampling voltage is carried out.
Since there is no invalid domain near [which becomes a
problem by the external operational amplifier etc.] VCCE/
VSS, conversion by the full range is possible in this sample
& hold circuit.
When A-D conversion is finished, the converters can generate a DMA transfer request, as well as an interrupt.
The microcomputer contains 16-channel A-D0 converters
with 10-bit resolution. In addition to single conversion on
each channel, continuous A-D conversion on a combined
group of N (N = 1-16) channels is possible. The A-D converted value can be read out in either 10-bit or 8-bit.
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.

4-channel High-speed Serial I/Os
The microcomputer contains 4 channels of serial I/Os consisting of four channels that can be set for CSIO mode
(clock-synchronized serial I/O) or UART mode (asynchronous serial I/O) and two other channels 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.

Error detection
CSIO mode : Overrun error only
UART mode : Overrun, parity, and framing errors
(The error-sum bit indicates which error has occurred)
Fixed cycle clock
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.

8-level Interrupt Controller
Real-time Debugger (RTD)
The Interrupt Controller controls interrupt requests from
each internal peripheral I/O (23 sources) by using eight priority levels assigned to each interrupt source, including interrupts prohibition. In addition to these interrupts, it handles
System Break Interrupt (SBI), Reserved Instruction Exception (RIE), and Address Exception (AE) as nonmaskable interrupts.
The Real-time Debugger (RTD) provides 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
Port input threshold level select function
The Wait Controller supports access to external devices.
For access to an external extended area of up to 1Mbytes
(during external extended or processor mode), the Wait
Controller controls bus cycle extension by inserting one to
four wait cycles and using external WAIT# signal input.
The port input level switch function sets the port threshold
value to 3 different voltage levels (Schmidt ON/OFF selection also available).
