Figure 3.1 shows a memory map of the M32C/87 Group (M32C/87, M32C/87A, M32C/87B).
The M32C/87 Group (M32C/87, M32C/87A, M32C/87B) has 16-Mbyte address space from addresses 000000h to
FFFFFFh.
The internal ROM is allocated in lower addresses, beginning with address FFFFFFh. For example, a 512-Kbyte
internal ROM area is allocated in addresses F80000h to FFFFFFh.
The fixed interrupt vectors are allocated in addresses FFFFDCh to FFFFFFh. They store the starting address of each
interrupt routine. Refer to 11. Interrupts for details.
The internal RAM is allocated higher addresses, beginning with address 000400h. For example, a 48-Kbyte internal
RAM area is allocated in addresses 000400h to 00C3FFh. The internal RAM is used not only for storing data but for
the stacks when subroutines are called or when interrupt requests are acknowledged.
SFRs are allocated in addresses 000000h to 0003FFh. The peripheral function control registers such as for I/O ports,
A/D converters, serial interfaces, timers are allocated here. All blank spaces within SFRs are reserved and cannot be
accessed by users.
The special page vectors are allocated addresses FFFE00h to FFFFDBh. They are used for the JMPS instruction and
JSRS instruction. Refer to the Renesas publication M32C/80 Series Software Manual for details.
