General-purpose input/outputs
The STM32W108 has 24 multi-purpose GPIO pins that may be individually configured as:

The basic structure of a single GPIO is illustrated in
Figure 8.
A Schmitt trigger converts the GPIO pin voltage to a digital input value. The digital input
signal is then always routed to the GPIO_PxIN register; to the alternate inputs of associated
peripheral devices; to wake detection logic if wake detection is enabled; and, for certain
pins, to interrupt generation logic. Configuring a pin in analog mode disconnects the digital
input from the pin and applies a high logic level to the input of the Schmitt trigger.
Only one device at a time can control a GPIO output. The output is controlled in normal
output mode by the GPIO_PxOUT register and in alternate output mode by a peripheral
device. When in input mode or analog mode, digital output is disabled.
