3. Memory
Figure 3.1 shows a memory map of the M32C/84 group (M32C/84, M32C/84T).
The M32C/84 group (M32C/84, M32C/84T) provides 16-Mbyte address space from addresses 000000
FFFFFF
.
16
The internal ROM is allocated lower addresses beginning with address FFFFFF
Kbyte internal ROM is allocated in addresses FF0000
The fixed interrupt vectors are allocated addresses FFFFDC
of each interrupt routine. Refer to 11. Interrupt for details.
The internal RAM is allocated higher addresses beginning with address 000400
Kbyte internal RAM is allocated addresses 000400
when the subroutine is called or an interrupt is acknowleged.
SFR, consisting of control registers for peripheral functions such as I/O port, A/D converter, serial I/O, and
timers, is allocated addresses 000000
cannot be accessed by users.
The special page vectors are allocated addresses FFFE00
tion and JSRS instruction. Refer to the Renesas publication M32C/80 Series Software Manual for details.
In memory expansion mode and microprocessor mode, some spaces are reserved and cannot be ac-
cessed by users.

2. In memory expansion mode.
This space becomes external space in microprocessor mode.
3. Additional 4-Kbyte space is provided in flash memory version for storing data.
This space can be used in single-chip mode and memory expansion mode.
This space becomes reserved space in microprocessor mode.
4. This space can be used in single-chip mode and memory expansion mode.
