interface
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 cor-
responding to each common signal, is
supplied to driver serially.

Data interface
Used for data transfer between the MPU and
KS0076B. These terminals are for data bus
with bidirectional three-state. Initial 4 bit
(DB0-DB3) are not used during 4-bit operation
(DB7 can be used as a busy flag)
