Description
Mitsubishi microcomputers
M16C / 62 Group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
The M16C/62 group of single-chip microcomputers are built using the high-performance silicon gate CMOS
process using a M16C/60 Series CPU core and are packaged in a 100-pin plastic molded QFP. These
single-chip microcomputers operate using sophisticated instructions featuring a high level of instruction
efficiency. With 1M bytes of address space, they are capable of executing instructions at high speed. They
also feature a built-in multiplier and DMAC, making them ideal for controlling office, communications, indus-
trial equipment, and other high-speed processing applications.
The M16C/62 group includes a wide range of products with different internal memory types and sizes and
various package types.

Central Processing Unit (CPU)
The CPU has a total of 13 registers shown in Figure 1.5.1. Seven of these registers (R0, R1, R2, R3, A0,
A1, and FB) come in two sets; therefore, these have two register banks.

Figure 1.5.1. Central processing unit register
(1) Data registers (R0, R0H, R0L, R1, R1H, R1L, R2, and R3)
Data registers (R0, R1, R2, and R3) are configured with 16 bits, and are used primarily for transfer and
arithmetic/logic operations.
Registers R0 and R1 each can be used as separate 8-bit data registers, high-order bits as (R0H/R1H),
and low-order bits as (R0L/R1L). In some instructions, registers R2 and R0, as well as R3 and R1 can
use as 32-bit data registers (R2R0/R3R1).
(2) Address registers (A0 and A1)
Address registers (A0 and A1) are configured with 16 bits, and have functions equivalent to those of data
registers. These registers can also be used for address register indirect addressing and address register
relative addressing.
In some instructions, registers A1 and A0 can be combined for use as a 32-bit address register (A1A0).
