Power supply

18~25

D7~D0

The pin is the data bus to be connected to the MPU.

26

RD

This Pin is MCU interface input .This pin will be read signal

27

WR

This Pin is MCU interface input .This pin will be write signal.

28

A0

This is connect to the least significant bit of the normal MPU address bus,
and it determines whether the data bits are data or command.

29

RST

When/RES is set to "L", the settings are initialized

30

CS

This is the chip select signal
