Function Description
Switches between the master chip and the slave
chip.
Exchanges synchronizing signals (LCD-to-AC
signals) in connecting cascades.
This pin is for output if the chip is the master, and for
input if the chip is the slave.
Data inputs/outputs
This pin is used for switching 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, it performs switching 68/80
series modes.
High level : 68 series MPU interface
Low level : 80 series MPU interface
68 series mode : Enable signal
80 series mode : Read enable signal
68 series mode : Read/Write signal
