Special Function Register (SFR) Area
The Special Function Register area in the zero page contains control
registers such as I/O ports and timers.
RAM
RAM is used for data storage and for stack area of subroutine calls
and interrupts.
ROM
The first 128 bytes and the last 4 bytes of ROM are reserved for
device testing and the rest is user area for storing programs. In the
flash memory version, program and erase can be performed in the
reserved area.
Interrupt Vector Area
The interrupt vector area contains reset and interrupt vectors.
Zero Page
Access to this area with only 2 bytes is possible in the zero page
addressing mode.
Special Page
Access to this area with only 2 bytes is possible in the special page
addressing mode.
Refer to page 74 for the memory map of memory expansion and
