This pin is used for GPIO. It is
individually programmed as input or
output and is also used individually
as an interrupt input. Each Port A
pin, when programmed as output is
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.
