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.
