Output
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
negative PWM 2. This signal is
multiplexed with PA6.
Event Counter Signal to Timer 2.
This signal is multiplexed with PA6.

Power Supply.
Ground.
This pin is used by the EMAC for the
MII Interface to the PHY (physical
layer). Carrier Sense is an
asynchronous signal.
This pin is used by the EMAC for the
MII Interface to the PHY. Collision
Detect is an asynchronous signal.
This pin is used by the EMAC for the
MII Interface to the PHY. Transmit
Data is synchronous to the rising-
edge of Tx_CLK.
