Notes:
1. Because there is only a single alternate function for each Port A pin, the Alternate Function Set registers are not
implemented for Port A. Enabling alternate function selections as described in the Port A–C Alternate Function
Subregisters section on page 43 automatically enables the associated alternate function.
2. Whether PA0/PA6 take on the timer input or timer output complement function depends on the timer configura-
tion as described in the Timer Pin Signal Operation section on page 83.
3. Because there are at most two choices of alternate function for any pin of Port B, the Alternate Function Set reg-
ister AFS2 is implemented but not used to select the function. Also, alternate function selection as described in
the Port A–C Alternate Function Subregisters section on page 43 must also be enabled.
4. V_REF is available on PB5 in 28-pin products only.
5. Because there are at most two choices of alternate function for any pin of Port C, the Alternate Function Set reg-
ister AFS2 is implemented but not used to select the function. Also, Alternate Function selection as described in
the Port A–C Alternate Function Subregisters section on page 43 must also be enabled.
6. V_REF is available on PC2 in 20-pin parts only.
