Note: 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
Port A–D Alternate Function Sub-Registers on page 42 automatically enables the associated
alternate function.
* Whether PA0/PA6 take on the timer input or timer output complement function depends on the
timer configuration as described in Timer Pin Signal Operation on page 75.
