LCD voltage booster (optional), boost capacitor, negative
pin. If using the LCD voltage booster, connect a 22 nF ca-
pacitor between LCD_BCAP_N and LCD_BCAP_P.
LCD voltage booster (optional), boost capacitor, positive
pin. If using the LCD voltage booster, connect a 22 nF ca-
pacitor between LCD_BCAP_N and LCD_BCAP_P.
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.
LCD driver common line number 0.
