Figure 3.1
Figure 3.1 is a Memory Map of R8C/36W Group. The R8C/36W 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 64-Kbyte internal ROM area is allocated addresses 04000h to 13FFFh.
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 (the SFR areas
for the CAN, DTC, and other modules). Peripheral function control registers are allocated here. All unallocated
spaces within the SFRs are reserved and cannot be accessed by users.
