3.2
R8C/15 Group
Figure 3.2 is a Memory Map of R8C/15 Group. The R8C/15 group provides 1-Mbyte address space from
addresses 00000h to FFFFFh.
The internal ROM (program area) is allocated lower addresses beginning with address 0FFFFh. For
example, a 16-kbyte internal ROM 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 ROM (data area) is allocated addresses 02400h to 02BFFh.
The internal RAM is allocated higher addresses beginning with address 00400h. For example, a 1-kbyte
internal RAM is allocated addresses 00400h to 007FFh. The internal RAM is used not only for storing
data but for calling subroutines and stacks when interrupt request is acknowledged.
Special function registers (SFR) are allocated addresses 00000h to 002FFh. The peripheral function
control registers are allocated them. All addresses, which have nothing allocated within the SFR, are
reserved area and cannot be accessed by users.
