Mitsubishi microcomputers
M16C / 62T Group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Memory
Operation of Functional Blocks
The M16C/62T 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.
Memory
Figure 1.4.1 is a memory map of the M16C/62T group. The address space extends the 1M bytes from
address 0000016 to FFFFF16.
Internal ROM is located as the following, in M30623M4T-XXXGP from address F800016 to FFFFF16 (32K
bytes), in M30622M8T/M8V-XXXFP and M30623M8T/M8V-XXXGP from address F000016 to FFFFF16
(64K bytes), in M30622MCT/MCV-XXXFP and M30623MCT/MCV-XXXGP from address E000016 to
FFFFF16 (128K bytes).
_______
The vector table for fixed interrupts such as the reset and NMI are mapped to FFFDC16 to FFFFF16. The
starting address of the interrupt routine is stored here. The address of the vector table for timer interrupts,
etc., can be set as desired using the internal register (INTB). See the section on interrupts for details.
Internal RAM is located as the following, in M30623M4T-XXXGP from address 0040016 to 00FFF16 (3K
bytes), in M30622M8T/M8V-XXXFP and M30623M8T/M8V-XXXGP from address 0040016 to 013FF16 (4K
bytes), in M30622MCT/MCV-XXXFP and M30623MCT/MCV-XXXGP from address 0040016 to 017FF16
(5K bytes). In addition to storing data, the RAM also stores the stack used when calling subroutines and
when interrupts are generated.
The SFR area is mapped to 0000016 to 003FF16. This area accommodates the control registers for
peripheral devices such as I/O ports, A-D converter, serial I/O, and timers, etc. Figures 1.7.1 to 1.7.3 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 FFE0016 to FFFDB16. If the starting addresses of subroutines
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 M30623MCT/MCV-XXXGP, the following spaces cannot be used.
The space between 0100016 and 03FFF16 (Memory expansion and microprocessor modes)
The space between D000016 and D7FFF16 (Memory expansion mode)
But the M16C/62T group is not guaranteed to operate in memory expansion and microprocessor modes.
