Bias voltage level for LCD driving
Segent signal output for LCD driving
Common signal output for LCD driving
Both pin 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
transfered 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.
Start enable signal to read or write the data
R/W signal input is used to select the read/write
mode
register selection input
Used for data transfer between the MPU and
KS0068. These terminals are for data bus with
bidirectional three-state.
