3. Memory
Figure 3.1 is a memory map of this MCU. This MCU provides 1-Mbyte address space from addresses
00000 to FFFFF
16
The internal ROM is allocated lower addresses beginning with address 0FFFF
internal ROM is allocated addresses from 0C000
The fixed interrupt vector table is allocated addresses 0FFDC
address of each interrupt routine.
The internal RAM is allocated higher addresses beginning with address 00400
internal RAM is allocated addresses 00400
data, but for calling subroutines and stacks when interrupt request is acknowledged.
Special function registers (SFR) are allocated addresses 00000
control registers are located them. All addresses, which have nothing allocated within the SFR, are re-
served area and cannot be accessed by users.
