3. Memory
Figure 3.1 shows a Memory Map. 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
128-Kbyte internal ROM is allocated to the addresses from E0000h to FFFFFh.
As for the flash memory version, 4-Kbyte space (block A) exists in 0F000h to 0FFFFh. 4-Kbyte space is
mainly for storing data. In addition to storing data, 4-Kbyte space also can store programs.
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 Special Function Registers (SFRs) are 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 accessed by user.
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 M16C/60, M16C/20, M16C/Tiny Series Software Manual.
In memory expansion and microprocessor modes, some areas are reserved for future use and cannot be
used by users.

Capacity
1. During memory expansion mode or microprocessor mode, cannot be used.
2. In memory expansion mode, cannot be used.
3. As for the flash memory version, 4-Kbyte space (block A) exists.
4. When using the masked ROM version, write nothing to internal ROM area.
5. Shown here is a memory map for the case where the PM10 bit in the PM1 register is 1 (block A enabled, addresses 10000h to
Aug 25, 2006
26FFFh for CS2 area).
M16C/6N Group (M16C/6N5) has no device model expanded over 192 Kbytes of the internal ROM.
Accordingly, set the PM13 bit to 0.
