Function Description

Switches between the master c hi p and the slave
chip.
Exchanges synchronizing signals (LCD-to-AC
signals) in connecting c ascades.
This pin is for output if the chip is the master, and for
input if the chip is t he slave.
Data inputs/outputs

This pin is used for switchi ng between the display
data and the instruction.
High level : Display data
Low level : Instruction
This pin performs reset at the edge of the low-level
pulse. At that level, i t performs switching 68/80
series modes.
High level : 68 series MPU int erface
Low level : 80 series MPU interfac e
68 series mode : Enable s i gnal
80 series mode : Read enable si gnal
