LCD_BCAP_N
PA13
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_BCAP_P
PA12
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_BEXT
PA14
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.
