Memory

Figure 3.1 is a Memory Map of each group. Each group has a 1-Mbyte address space from addresses 00000h to

FFFFFh. The internal ROM (program ROM) is allocated lower addresses, beginning with address 0FFFFh. For

example, a 48-Kbyte internal ROM area is allocated addresses 04000h to 0FFFFh.

The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. The starting address of each interrupt

routine is stored here.

The internal ROM (data flash) is allocated addresses 03000h to 03FFFh.

The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 6-Kbyte internal

RAM area is allocated addresses 00400h to 01BFFh. The internal RAM is used not only for data storage but also as a

stack area when a subroutine is called or when an interrupt request is acknowledged.

Special function registers (SFRs) are allocated addresses 00000h to 002FFh and 02C00h to 02FFFh. Peripheral

function control registers are allocated here. All unallocated spaces within the SFRs are reserved and cannot be

accessed by users.

Notes:

1. Data flash indicates block A (1 Kbyte), block B (1 Kbyte),

block C (1 Kbyte), and block D (1 Kbyte).

2. Blank spaces are reserved. No access is allowed.
