GPIO
The STM32W108 has 24 multi-purpose GPIO pins that may be individually configured as
Input, Output, Analog or Alternate.
To migrate to StdPeriph_Driver, the GPIO registers are split into registers for GPIO and
others for external interrupts EXTI.
The following table provides an overview of the HAL vs StdPeriph functions that enable a
standard use of the GPIO features. The StdPeriph functions provide an equivalent for HAL
code providing the same functionality.
