3. Memory
Figure 3.1 is a memory map of this MCU. This MCU provides 1-Mbyte address space from addresses
0000016 to FFFFF16.
The internal ROM is allocated lower addresses beginning with address 0FFFF16. For example, a 16-Kbyte
internal ROM is allocated addresses from 0C00016 to 0FFFF16.
The fixed interrupt vector table is allocated addresses 0FFDC16 to 0FFFF16. They store the starting
address of each interrupt routine.
The internal RAM is allocated higher addresses beginning with address 0040016. For example, a 1-Kbyte
internal RAM is allocated addresses 0040016 to 007FF16. The internal RAM is used not only for storing
data, but for calling subroutines and stacks when interrupt request is acknowledged.
Special function registers (SFR) are allocated addresses 0000016 to 002FF16. The peripheral function
control registers are located them. All addresses, which have nothing allocated within the SFR, are re-
served area and cannot be accessed by users.
