Receive Error: In internal PHY mode, this pin
can be configured to display the respective
internal MII signal.
Receive Error: In external PHY mode, the signal
on this pin is input from the external PHY and
indicates a receive error in the packet.
Transmit Enable: In internal PHY mode, this pin
can be configured to display the respective
internal MII signal.
Transmit Enable: In external PHY mode, this pin
output to the external PHY and indicates valid
data on TXD[3:0].
Receive Data Valid: In internal PHY mode, this
pin can be configured to display the respective
internal MII signal.
Receive Data Valid: In external PHY mode, the
signal on this pin is input from the external PHY
and indicates valid data on RXD[3:0].
Receive Clock: In internal PHY mode, this pin
can be configured to display the respective
internal MII signal.
Receive Clock: In external PHY mode, this pin
is the receiver clock input from the external PHY.
Carrier Sense: In internal PHY mode, this pin
can be configured to display the respective
internal MII signal.
Carrier Sense: In external PHY mode, the signal
on this pin is input from the external PHY and
indicates a network carrier.
