Both pins connected to Rf resistor or ceramic

resonator for internal oscillator circuit. 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.

bi-directional three-state. Initial 4 bit (DB0 - DB3)

are not used during 4 bit operation (DB7 can be

used as a busy flag)
