Description
This pin can be used for general-
purpose I/O. It can be individually
programmed as input or output
and can also be used individually
as an interrupt input. Each Port A
pin, when programmed as output,
can be selected to be an open-
drain or open-source output.
This pin is used by Timer 3 for
PWM 0. This signal is multiplexed
with PA0.
This pin is used by Timer 3 for
Output Compare 0. This signal is
multiplexed with PA0.
