3. Memory
Figure 3.1 is a memory map of this MCU. The address space extends the 1M bytes from address 00000
to FFFFF .
16
The internal ROM is allocated in a lower address direction beginning with address 0FFFF
a 16-Kbyte internal ROM is allocated to the addresses from 0C000
The fixed interrupt vector table is allocated to the addresses from 0FFDC
the start address of each interrupt routine here.
The internal RAM is allocated in an upper address direction beginning with address 00400
a 1-Kbyte internal RAM is allocated to the addresses from 00400
the internal RAM also stores the stack used when calling subroutines and when interrupts are generated.
Special function registers (SFR) are allocated to the addresses from 00000
tion control registers are located here. Of the SFR, any space which has no functions allocated is reserved
for future use and cannot be used by users.
