The wire between OSC1 and Rf and the wire between

OSC2 and Rf should be as short as possible.

Keep OSCR open.

The wire between OSC2 and OSCR should be as short

as possible. Keep OSC1 open.

Note 7:

The maximum value of the voltage multiplier input voltage should be set at 3.5 V, and the

minimum value of the voltage multiplier input voltage should be set so that the voltage

multiplier output voltage meets the specification for the bias voltage for driving LCD after

contrast adjustment.

Note 8: If using the built-in contrast control circuit, control the circuit so that the voltage of VDD-V5 is the

minimum value of the bias voltage for driving LCD or higher.

Note 9: For 1/4 bias, V2 and V3B pins are short-circuited. V3A pin is open.

For 1/5 bias, V3A and V3B pins are short-circuited. V2 pin is open.
