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.

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.
