Figure 3.1 shows a memory map of the M32C/80 Group.
The M32C/80 Group provides 16-Mbyte address space addressed from 000000
The fixed interrupt vectors are allocated from address FFFFDC
dress of each interrupt routine.
The internal RAM is allocated from address 000400
allocated from address 000400
tine is called or an interrupt is acknowledged.
SFRs, consisting of control registers for peripheral functions such as I/O port, A/D converter, serial I/O,
timers, is allocated from address 000000
cannot be accessed by users.
The special page vector table is addressed from FFFE00
tion and JSRS instruction. Refer to the Renesas publication M32C/80 Series Software Manual for details.
In microprocessor mode, some spaces are reserved and cannot be accessed by users.
