Figure 3.1
Figure 3.1 is a Memory Map of R8C/1A Group. The R8C/1A 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.
