The Port A–D Alternate Function Subregister is accessed through the Port A–D Control
Register by writing
Port A–D Alternate Function subregisters enable the alternate function selection on pins.
If disabled, the pins function as GPIOs. If enabled, select one of four alternate functions
using Alternate Function Set subregisters 1 and 2, as described in the the
nate Function Set 1 Subregisters
Set 2 Subregisters
page 34 to determine the alternate functions associated with each port pin.
Do not enable alternate functions for GPIO port pins for which there is no associated Al-
ternate function. Failure to follow this guideline can result in unpredictable operation.
