O
LCD COM/SEG output driving voltage. If internal shunt resistor is
disabled, external resistors need to be supplied to V2, V3, V4, V5 . A
capacitor is suggestted for stable LCD voltage level.
I
External variable resistor connects between VDD3 and V6 to adjust
LCD maximun voltage level.
I
Microcontroller Positive power supply (+).
I
Negative power supply (-).
I
Negative power supply (-).
