Caution:
Port A–B Alternate Function 0 Subregisters
The Port A–B Alternate Function subregisters
Control registers by writing
nate Function subregisters select the alternate functions for the selected pins. To determine
the alternate function associated with each port pin, see
34.
You must not enable alternate function for GPIO port pins which do not have an associated
alternate function. Failure to follow this guideline may result in unpredictable operation.

These bits control the direction of the associated port pin. Port Alternate
Function operation overrides the Data Direction register setting.
Output. Data in the Port A–C Output Data register is driven onto the port
pin.
Input. The port pin is sampled and the value written into the Port A–C Input
Data register. The output driver is tristated.
