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]
Digital I/O
32.768 kHz crystal oscillator.
Select analog function with GPIO_PCCFGH[15:12]
Digital 32 kHz clock input source
Regulator output (1.8 V while awake, 0 V during deep sleep)
Pads supply (2.1-3.6 V)
1.25 V digital core supply decoupling
Digital I/O. Disable REG_EN with GPIO_DBGCFG[4]
Timer 1 Channel 4 output
Enable timer output with TIM1_CCER
Select alternate output function with GPIO_PACFGH[15:12]
Disable REG_EN with GPIO_DBGCFG[4]
Timer 1 Channel 4 input. (Cannot be remapped.)
External regulator open drain output. (Enabled after reset.)
