In case of external frequency use only, the frequency is input to OSC1 terminal. Clock output terminal for the serially transferred data to be latched to the driver. Clock output terminal used when D terminal data output shifts the inside of the driver. The alternating signal to convert LCD drive waveform to AC. Character pattern data, which is corresponding to each common signal, is supplied to driver serially. IZ0065 LCD LCD Resistor or Ceramic Resonator INTERFACE Power Supply
