Media Dependent Interface[0]:
1000BASE-T:
In MDI configuration, MDI[0]+/-corresponds to BI_DA+/-
and in MDI-X configuration MDI[0]+/- corresponds to
BI_DB+/-.
100BASE-TX:
In MDI configuration, MDI[0]+/- is used for the transmit
pair and in MDIX configuration MDI[0]+/- is used for the
receive pair.
10BASE-T:
In MDI configuration, MDI[0]+/- is used for the transmit
pair and in MDI-X configuration MDI[0]+/- is used for the
receive pair.
Media Dependent Interface[1]:

In MDI configuration, MDI[1]+/- corresponds to BI_DB+/-
and in MDI-X configuration MDI[1]+/- corresponds to
BI_DA+/-.
100BASE-TX:
In MDI configuration, MDI[1]+/- is used for the receive
pair and in MDI-X configuration MDI[1]+/- is used for the
transmit pair.
10BASE-T:
In MDI configuration, MDI[1]+/- is used for the receive
pair and in MDI-X configuration MDI[1]+/- is used for the
transmit pair.
Media Dependent Interface[3:2]:
1000BASE-T:
In MDI and in MDI-X configuration, MDI[2]+/-
corresponds to BI_DC+/- and MDI[3]+/- corresponds to
BI_DD+/-.

XTAL In/Out
These pins can be driven by an external 25 MHz crystal or
driven by an external MOS level 25 MHz oscillator. Used to
drive the PHY.
Positive side of the high speed differential debug port for
the PHY.
PHY Termination
This pin should be connected through a 4.99 K +-1%
resister to ground.
This is a 3.3 V dc input signal. Asserting DEV_OFF_N
puts the 82574 in device disable mode. Note that this
pin is asynchronous.
