Description

LCD segment outputs. Output resistance: £18 kW

22 to 29 C1 to C8 O LCD common LCD common outputs. Output resistance: £6kW

Serial data input. Serial data is input through this pin in 8-bit

units from the MSB side. For details on the configuration of

input data, see "Command Configuration" and "Input Display

Data Configuration".

Command/data select input. When this pin is at the "H" level,

39

C/D

serial input data from SI is recognized as a command. When

I Microcontroller

this pin is at the "L" level, serial input data from SI is recognized

as display data.

Shift clock input. Data at SI and C/D pins are read synchronizing

SHT

with the rising edge of this clock.

I Microcontroller

Display data is output to the S0 pin synchronizing with the

falling edge of this clock.

Serial data output. This pin outputs display data. For details on

the configuration of output data, see "Output Display Data

Configuration". This pin can be set to high impedance by the

SOE/D command.

Chip select input. When this pin is at the "H" level, chip is

selected, and command and display data can be transferred.

When this pin is at the "L" level, SO output is set to high

CS

I Microcontroller impedance, SHT input is set to the "H" level, and SI and C/D

inputs are set to the "L" level, and command and display data

transfer are disabled.

Reset input.
