Memory
Special function register (SFR) area
The SFR area in the zero page contains control registers such as
I/O ports and timers.
RAM
RAM is used for data storage and for a stack area of subroutine
calls and interrupts.
ROM
The first 128 bytes and the last 2 bytes of ROM are reserved for
device testing and the rest is a user area for storing programs.
The reserved ROM area can program/erase in the flash memory
version.
Interrupt vector area
The interrupt vector area contains reset and interrupt vectors.
Zero page
The 256 bytes from addresses 000016 to 00FF16 are called the
zero page area. The internal RAM and the special function regis-
ters (SFR) are allocated to this area.
The zero page addressing mode can be used to specify memory
and register addresses in the zero page area. Access to this area
with only 2 bytes is possible in the zero page addressing mode.
Special page
The 256 bytes from addresses FF0016 to FFFF16 are called the
special page area. The special page addressing mode can be
used to specify memory addresses in the special page area. Ac-
cess to this area with only 2 bytes is possible in the special page
addressing mode.
