Segment driver outputs
The S79/COM10 and S80/COM9 pins can be used as common
driver outputs under the “set display technique” instruction.
Common driver outputs
Oscillator connection. An oscillator circuit is formed by connecting
an external resistor and capacitor at this pin.
Serial data transfer inputs. These pins are connected to the
microcontroller.
Reset signal input
LCD drive 4/4 bias voltage (high level) supply pin. The level on
this pin can be changed by the display contrast adjustment circuit.
However, V
external power must not be applied to this pin since the pin circuit
includes the display contrast adjustment circuit.
LCD drive 3/4 bias voltage (middle level) supply pin. This pin can
be used to supply the 3/4 V
LCD drive 2/4 bias voltage (middle level) supply pin. This pin can
be used to supply the 2/4 V
LCD drive 1/4 bias voltage (middle level) supply pin. This pin can
be used to supply the 1/4 V
Logic block power supply connection. Provide a voltage of
between 2.7 and 6.0 V.
LCD driver block power supply connection. Provide a voltage of
between 7.0 and 10.0 V when the display contrast adjustment
circuit is used and provide a voltage of between 4.5 and 10.0 V
when the circuit is not used.
Power supply connection. Connect to ground.

CE: Chip enable
CL: Synchronization clock
DI: Transfer data
Display off
Serial data transfer is disabled.
The OSC pin oscillator is stopped.
Display on after a “display on/off control” (display on state
setting) instruction is executed.
Serial data transfers are enabled.
The OSC pin oscillator operates.
