Figure 3.1 shows a memory map of the M32C/83 group (M32C/83, M32C/83T).
M32C/83 group (M32C/83, M32C/83T) provides 16-Mbyte address space from addresses 000000
FFFFFF
The internal ROM is allocated lower addresses beginning with address FFFFFF
Kbyte internal ROM is allocated addresses FF0000
The fixed interrupt vectors are allocated addresses FFFFDC
of each interrupt routine. Refer to 10. Interrupts 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 acknowledged.
SFR, consisting of control registers for peripheral functions such as I/O port, A/D conversion, serial I/O, and
timers, is allocated addresses 000000
SFR, are reserved space and cannot be accessed by users.
The special page vectors are allocated addresses FFFE00
tion and JSRS instruction. Refer to the Renesas publication Software Manual for details.
In memory expansion mode and microprocessor mode, some space are reserved and cannot be accessed
by users.
