LCD segment outputs. Output resistance: £18 kW
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,
serial input data from SI is recognized as a command. When
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
with the rising edge of this clock.
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
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.
Setting this pin at the "L" level resets to initial status.
Test signal inputs. Set these pins to the same potential as V
unconnected. An error may occur by another setting.
Pins for an 80 kHz RC oscillation circuit. Connect resistors and a
capacitor as shown below.
