Notes:
1. Because there is only a single alternate function for each Port A and Port D (PD0) pin, the Alternate Function
Set registers are not implemented for Port A and Port D (PD0). Enabling alternate function selections (as
described in the Port A–D Alternate Function Subregisters section on page 42) automatically enables the asso-
ciated alternate function.
2. Because there are at most two choices of alternate functions for any Port B pin, the AFS2 Alternate Function Set
Register is implemented but is not used to select the function. Additionally, alternate function selection (as
described in the Port A–D Alternate Function Subregisters section on page 42) must also be enabled.
3. Because there are at most two choices of alternate functions for any Port C pin, the AFS2 Alternate Function Set
Register is implemented but is not used to select the function. Additionally, alternate function selection (as
described in the Port A–D Alternate Function Subregisters section on page 42) must also be enabled.
