3.
Figure 3.1 is a Memory Map of R8C/2G Group. The R8C/2G group has 1 Mbyte of address space from addresses
00000h to FFFFFh.
The internal ROM is allocated lower addresses, beginning with address 0FFFFh. For example, a 16-Kbyte internal
ROM area is allocated addresses 0C000h to 0FFFFh.
The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each
interrupt routine.
The internal RAM is allocated higher addresses beginning with address 00400h. For example, a 1-Kbyte internal RAM
area is allocated addresses 00400h to 007FFh. 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 (SFRs) are allocated addresses 00000h to 002FFh. The peripheral function control registers
are allocated here. All addresses within the SFR, which have nothing allocated are reserved for future use and cannot
be accessed by users.
