Segment driver outputs.
The S59/COM10 and S60/COM9 pins can be used as common
driver outputs under the “set display technique” instruction.
Common driver outputs.
Oscillator connections. An oscillator circuit is formed by
connecting an external resistor and capacitor at these pins.
Serial data transfer inputs. These pins are connected to the
microcontroller.
Reset signal input.
• When RES is low (V
• When RES is high (V
Used for applying the LCD drive 3/4 bias voltage externally.
Used for applying the LCD drive 2/4 bias voltage externally.
Used for applying the LCD drive 1/4 bias voltage externally.
Logic block power supply connection. Provide a voltage of
