8.2 MEMORY
8.2.1 Special Function Register (SFR) Area
The special function register (SFR) area in the zero page includes
control registers such as I/O ports and timers.
8.2.2 RAM
RAM is used for data storage and for stack area of subroutine calls
and interrupts.
8.2.3 ROM
ROM is used for storing user programs as well as the interrupt vector
area.
8.2.4 OSD RAM
RAM used for specifying the character codes and colors for display.
8.2.5 OSD ROM
ROM used for storing character data for display.
8.2.6 Interrupt Vector Area
The interrupt vector area contains reset and interrupt vectors.
8.2.7 Zero Page
The zero page addressing mode can be used to specify memory and
register addresses in the zero page area. Access to this area is pos-
sible with only 2 bytes in the zero page addressing mode.
8.2.8 Special Page
The special page addressing mode can be used to specify memory
addresses in the special page area. Access to this area is possible
with only 2 bytes in the special page addressing mode.
8.2.9 ROM Correction Memory (RAM)
This is used as the program area for ROM correction.
