Figure 3.2
Figure 3.2 shows a Memory Map of R8C/21 Group. The R8C/21 Group has 1 Mbyte of address space from
address 00000h to FFFFFh.
The internal ROM (program ROM) is allocated lower addresses, beginning with address 0FFFFh. For example, a
48-Kbyte internal ROM is allocated addresses 04000h to 0FFFFh.
The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each
interrupt routine.
The internal ROM (data flash) is allocated addresses 02400h to 02BFFh.
The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2.5-Kbyte
internal RAM is allocated addresses 00400h to 00DFFh. The internal RAM is used not only for storing data but
also for calling subroutines and as stacks when interrupt requests are acknowledged.
Special function registers (SFR) are allocated addresses 00000h to 002FFh. The peripheral function control
registers are allocated them. All addresses within the SFR, which have nothing allocated are reserved for future
use and cannot be accessed by users.

NOTES:
1. Data flash block A (1 Kbyte) and B (1 Kbyte) are shown.
2. The blank regions are reserved. Do not access locations in these regions.
3. Do not use addresses 20000h to 23FFFh because these areas are used for the emulator debugger. Refer to 23. Notes on
