Figure 3.1
Figure 3.1 shows the Memory Map. The R8C/36T-A Group has a 1-Mbyte address space from addresses 00000h to
FFFFFh. Up to 32 Kbytes of the internal ROM (program ROM) is allocated at lower addresses, beginning with
address 0FFFFh. The area in excess of 32 Kbytes is allocated at higher addresses, beginning with address 10000h.
For example, a 64-Kbyte internal ROM is allocated at addresses 08000h to 17FFFh.
The fixed interrupt vector table is allocated at addresses 0FFDCh to 0FFFFh. The start address of each interrupt
routine is stored here.
The internal ROM (data flash) is allocated at addresses 07000h to 07FFFh.
The internal RAM is allocated at higher addresses, beginning with address 00400h. For example, a 6-Kbyte
internal RAM is allocated at 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 at addresses 00000h to 02FFFh and addresses 06800h to 06FFFh.
Peripheral function control registers are allocated here. All unallocated locations within the SFRs are reserved and
cannot be accessed by users.

1. Data flash indicates block A (1 Kbyte), block B (1 Kbyte), block C (1 Kbyte), and block D (1 Kbyte).
2. Addresses 06800h to 06FFFh are used for the ELC, DTC, and TSCU SFR areas.
3. The blank areas are reserved. No access is allowed.
