Memory
Figure 3.1 is a Memory Map of the M16C/30P group. The address space extends the 1 Mbyte from address 00000h to
FFFFFh.
The internal ROM is allocated in a lower address direction beginning with address FFFFFh. For example, a 64-Kbyte
internal ROM is allocated to the addresses from F0000h to FFFFFh.
The fixed interrupt vector table is allocated to the addresses from FFFDCh to FFFFFh. Therefore, store the start
address of each interrupt routine here.
The internal RAM is allocated in an upper address direction beginning with address 00400h. For example, a 5-Kbyte
internal RAM is allocated to the addresses from 00400h to 017FFh. In addition to storing data, the internal RAM also
stores the stack used when calling subroutines and when interrupts are generated. The SFR is allocated to the addresses
from 00000h to 003FFh. Peripheral function control registers are located here. Of the SFR, any area which has no
functions allocated is reserved for future use and cannot be used by users.
The special page vector table is allocated to the addresses from FFE00h to FFFDBh. This vector is used by the JMPS
or JSRS instruction. For details, refer to the
M16C/60 and M16C/20 Series Software Manual
.

NOTES:
1. During memory expansion and microprocessor modes, can be used.
2. In memory expansion mode, can be used.
3. As for the flash memory version, 4-Kbyte space (block A) exists.
4. Shown here is a memory map for the case where the PM10 bit in the PM1 register is “1” .
5. When using the masked ROM version, write nothing to internal ROM area.
6. When the PM13 bit is set to "0", the address of Internal ROM becomes D0000h, and when
the PM13 bit is set to "1", the address becomes C0000h.
