Function
V
When CR oscillation is performed, a resistor must be
connected externally. When the pin input is an external
clock, it must be input to OSC1.
Input voltage to the booster, from which the liquid crystal
display drive voltage is generated.
Vci is reference voltage and power supply for the booster.
Vci = 1.0V to 5.0V
Voltage input to the Vci pin is boosted twice and output
When the voltage is boosted three times, the same capacity
as that of C1–C2 should be connected.

External capacitance should be connected when using the
booster.
Test pin. Should be wired to ground.
Voltage input to the Vci pin is boosted three times and
