8.2 MEMORY

8.2.1 Special Function Register (SFR) Area

The special function register (SFR) area in the zero page contains

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 for display is used for specifying the character codes and col-

ors to display.

8.2.5 OSD ROM

ROM for display is used for storing character data.

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

only 2 bytes is possible 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 with only 2

bytes is possible in the special page addressing mode.

8.2.9 ROM Correction Memory (RAM)

This is used as the program area for ROM correction.
