Figure 1.3.1. Memory map
The M16C/62A group accommodates certain units in a single chip. These units include ROM and RAM to
store instructions and data and the central processing unit (CPU) to execute arithmetic/logic operations.
Also included are peripheral units such as timers, serial I/O, D-A converter, DMAC, CRC calculation circuit,
A-D converter, and I/O ports.
The following explains each unit.
Figure 1.3.1 is a memory map of the M16C/62A group. The address space extends the 1M bytes from
address 00000
there is 128K bytes of internal ROM from E0000
the reset and NMI are mapped to FFFDC

internal register (INTB). See the section on interrupts for details.

eral devices such as I/O ports, A-D converter, serial I/O, and timers, etc. Figures 1.6.1 to 1.6.3 are location
of peripheral unit control registers. Any part of the SFR area that is not occupied is reserved and cannot be
used for other purposes.
The special page vector table is mapped to FFE00
or the destination addresses of jumps are stored here, subroutine call instructions and jump instructions
can be used as 2-byte instructions, reducing the number of program steps.
In memory expansion mode and microprocessor mode, a part of the spaces are reserved and cannot be
used. For example, in the M30622MCA-XXXFP, the following spaces cannot be used.
• The space between 01800
• The space between D0000
