Alternate functions that may be assigned to a Pin.

GPIO pins on the STM32F446RE may serve multiple functions. In addition to the default functionality, each pin can be assigned up to sixteen different alternate functions. The various functions for each pin are described in “Alternate Function”“ section of the STM32F446RE datasheet¹.

Alternate Function bit mapping is shown here².
