Figure 3.1 is a memory map of the M16C/28 Group. M16C/28 Group provides 1-Mbyte address space from
addresses 00000
FFFFF
Two 2-Kbyte internal ROM areas, block A and block B, are available in the flash memory version. The
blocks are allocated addresses F000
The fixed interrupt vector tables are allocated addresses FFFDC
dress of each interrupt routine. See the section on interrupts for details.
The internal RAM is allocated higher addresses beginning with address 00400
internal RAM is allocated addresses 00400
subroutine is called or an interrupt is acknowledged.
SFR, consisting of control registers for peripheral functions such as I/O port, A/D converter, serial I/O,
timers is allocated addresses 00000
accessed by users.
The special page vector table is allocated to the addresses FFE00
JMPS or JSRS instruction. For details, refer to the M16C/60 and M16C/20 Series Software Manual .
