LCD voltage booster (optional), boost capacitor, negative pin.
If using the LCD voltage booster, connect a 22 nF capacitor
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 capacitor
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.
