When crystal oscillation is performed, an external
resistor must be connected. When the pin input is an
external clock, it must be input to OSC1.
Inputs voltage to the booster to generate the liquid
crystal display drive voltage.
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, a capacitor
with the same capacitance as that of C1–C2 should be
connected here.
Voltage input to the Vci pin is boosted three times and
output.
