and ON-SCREEN DISPLAY CONTROLLER

FUNCTIONAL DESCRIPTION

Central Processing Unit (CPU)

This microcomputer uses the standard 740 Family instruction set.

Refer to the table of 740 Family addressing modes and machine

instructions or the SERIES 740 <Software> User’s Manual for de-

tails on the instruction set.

Machine-resident 740 Family instructions are as follows:

The FST, SLW instruction cannot be used.

The MUL, DIV, WIT and STP instructions can be used.

CPU Mode Register

The CPU mode register contains the stack page selection bit and

internal system clock selection bit. The CPU mode register is allo-

cated at address 00FB16.

MEMORY

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.

RAM

RAM is used for data storage and for stack area of subroutine calls

and interrupts.

ROM

ROM is used for storing user programs as well as the interrupt vector

area.

RAM for Display

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

ors to display.

ROM for Display

ROM for display is used for storing character data.

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 registers (SFR)

are allocated to this area.

The zero page addressing mode can be used to specify memory and

only 2 bytes is possible in the zero page addressing mode.

Special Page

The 256 bytes from addresses FF0016 to FFFF16 are called the spe-

cial page area. 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.
