High Frequency Crystal negative pin. Also used as external
optional clock input pin.
High Frequency Crystal positive pin.
I2C0 Serial Clock Line input / output.
I2C0 Serial Data input / output.
I2C1 Serial Clock Line input / output.
I2C1 Serial Data input / output.
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.
If AVDD is used directly as the LCD supply voltage, this pin
may be left unconnected or used as a GPIO.
