For input data, input a logic "0" and a logic "1" to LCD display bits alternately.

External resistor for oscillation : RO = 62 kW

External capacitor for oscillation : CO = 0.01 mF

The tr, and tf time for the CLOCK2, DATA and LOAD pins must be less than 20ns.

The current that flows through the external resistor and capacitor is not included.
