(PU)
In External PHY Mode, the signal on this pin is
input from the external PHY and indicates a
network carrier.
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output or a Schmitt-triggered input.

IS/O8
(PU)
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output or a Schmitt-triggered input.
Note:
This pin may be used to signal PME
when Internal PHY and PME Modes of
operation are in effect. Refer to
Chapter 5, "PME Operation," on
page 37 for additional information.
In Internal PHY Mode, this pin can be configured
to display the respective internal MII signal.

In External PHY Mode, this pin provides the
management data to/from the external PHY.
GPIO1
IS/O8/
OD8
(PU)
This General Purpose I/O pin is fully
programmable as either a push-pull output, an
open-drain output or a Schmitt-triggered input.
Note:
This pin may serve as the
PME_MODE_SEL input when Internal
PHY and PME Modes of operation are
in effect. Refer to Chapter 5, "PME
Operation," on page 37 for additional
information.
