Memory
Figure 1.4 is a memory map of the M306V8FJFP. The address space extends the 1M bytes from address
0000016 to FFFFF16.
The internal ROM is allocated in a lower address direction beginning with address FFFFF16. For example,
a 64 Kbytes internal ROM is allocated to the addresses from F000016 to FFFFF16.
The fixed interrupt vector table is allocated to the addresses from FFFDC16 to FFFFF16. Therefore, store
the start address of each interrupt routine here.
The internal RAM is allocated in an upper address direction beginning with address 0040016. For example,
a 10 Kbytes internal RAM is allocated to the addresses from 0040016 to 02BFF16. In addition to storing
data, the internal RAM also stores the stack used when calling subroutines and when interrupts are gener-
ated.
The SRF is allocated to the addresses from 0000016 to 003FF16. 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 FFE0016 to FFFDB16. This vector is used
by the JMPS or JSRS instruction. For details, refer to the “M16C/60 and M16C/20 Series Software Manual.”
In memory expansion and microprocessor modes, some areas are reserved for future use and cannot be
used by users.
