Analog pad supply (1.8V)
Digital I/O
Logic-level control for external Rx/Tx switch. The
STM32W108 baseband controls TX_ACTIVE and drives it
high (VDD_PADS) when in Tx mode.
Select alternate output function with GPIO_PCCFGH[7:4]
Active low chip reset (internal pull-up)
Digital I/O
32.768 kHz crystal oscillator
Select analog function with GPIO_PCCFGH[11:8]
Inverted TX_ACTIVE signal (see PC5)
Select alternate output function with GPIO_PCCFGH[11:8]
