Memory
Figure 3.1 shows a memory mapping of the R32C/157 Group.
The R32C/157 Group provides 4-Gbyte address space from 00000000h to FFFFFFFFh.
The internal ROM is allocated from address FFFFFFFFh to lower. For example, a 512-Kbyte internal ROM
is addressed from FFF80000h to FFFFFFFFh.
The fixed interrupt vectors are allocated from address FFFFFFDCh to FFFFFFFFh in which the starting
address of each interrupt handler is stored.
The internal RAM is allocated from address 00000400h to higher. For example, a 32-Kbyte internal RAM is
addressed from 00000400h to 000083FFh. Besides being used for data storage, the internal RAM functions
as stack(s) for a subroutine and/or an interrupt handler.
Special Function Registers (SFR), consisting of control registers for peripheral functions, are allocated from
address 00000000h to 000003FFh and from 00040000h to 0004FFFFh. Any blank spaces within the SFR
are reserved. No access is allowed.

Notes:
1. Additional two 4-Kbyte spaces (blocks A and B) for storing data are provided in the flash memory version.
2. The watchdog timer interrupt shares the vector table with the oscillation stop detection interrupt and low-
voltage detection interrupt.
