Figure 3.1 shows the memory map of the R32C/116 Group.
The R32C/116 Group provides a 4-Gbyte address space from 00000000h to FFFFFFFFh.
The internal ROM is mapped to the end of the memory map with the ending address fixed at FFFFFFFFh.
Therefore, the 1-Mbyte internal ROM is mapped from FFF00000h to FFFFFFFFh.
The fixed interrupt vector table which contains each start address of interrupt handlers is mapped from
FFFFFFDCh to FFFFFFFFh.
The internal RAM is mapped to the beginning of the memory map with the starting address fixed at
00000400h. Therefore, the 63-Kbyte internal RAM is mapped from 00000400h to 0000FFFFh. Besides
being used for data storage, the internal RAM functions as a stack(s) for subroutines and/or interrupt
handlers.
Special Function Registers (SFRs), which are control registers for peripheral functions, are mapped from
00000000h to 000003FFh, and from 00040000h to 0004FFFFh. Unoccupied SFR locations are reserved.
No access is allowed.
In memory expansion mode or microprocessor mode, some spaces are reserved for internal use and should
not be accessed.
