Description
LCD voltage booster (optional), boost output. If using the
LCD voltage booster, connect a 1 uF capacitor between
this pin and VSS.
An external LCD voltage may also be applied to this pin if
the booster is not enabled.
If AVDD is used directly as the LCD supply voltage, this
pin may be left unconnected or used as a GPIO.
