Segment outputs for displaying the display data transferred by serial data
input. The pins S1/P1 to S8/P8 can be used as general-purpose output ports
when so set up by the control data.
Common driver outputs.

Oscillator connection
An oscillator circuit is formed by connecting an external resistor and capacitor
to this pin.
Serial data transfer inputs. These
pins are connected to the control
microprocessor.

•INH = low (V
•INH = high (V
Note that serial data transfers can be performed when the
display is forced off by this pin.
Used to apply the LCD drive 2/3-bias voltage externally. This pin must be
connected to V LCD 2 when 1/2-bias drive is used.
Used to apply the LCD drive 1/3-bias voltage externally. This pin must be
connected to V LCD 1 when 1/2-bias drive is used.
Logic block power supply. Provide a voltage in the range 2.7 to 6.0 V.
LCD driver block power supply. Provide a voltage in the range 2.7 to 6.0 V.
Ground pin. Connect to ground.
