3. Memory
Figure 3.1 Memory Map
Figure 3.1 is a memory map of this MCU. This MCU provides 1-Mbyte address space from addresses
00000
The internal ROM (program ROM) is allocated lower addresses beginning with address 0FFFF
example, a 16-Kbyte internal ROM is allocated addresses from 0C000
The fixed interrupt vector table is allocated addresses 0FFDC
address of each interrupt routine.
The internal ROM (data flash) is allocated addresses from 02000
The internal RAM is allocated addresses beginning with address 00400
nal RAM is allocated addresses 00400
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.
