Operation of Functional Blocks
The M16C/60 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 1.6 is a memory map of the M16C/60 group. The address space extends the 1M bytes from address
0000016 to FFFFF16. From FFFFF16 down is ROM. (In the M30600M8-XXXFP, there is 64K bytes of
_______
internal ROM from F000016 to FFFFF16.) 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.
10K bytes of internal RAM is mapped to the space from 0040016 to 02BFF16. 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 periph-
eral devices such as I/O ports, A-D converter, serial I/O, and timers, etc. 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, the spaces between 02C0016 and 03FFF16, and between D000016 and
EFFFF16 are reserved and cannot be used. Likewise, the space between 02C0016 and 03FFF16 is re-
served when in microprocessor mode.
