MDI[0]-
I/O, D
Media Dependent Interface[0].
In 1000BASE-T mode in MDI configuration,
MDI[0]±
correspond to BI_DA±.
In MDIX configuration, MDI[0]± correspond
to BI_DB±.
In 100BASE-TX and 10BASE-T modes in
MDI configuration, MDI[0]± are used for the
transmit pair. In MDIX configuration,
MDI[0]± are used for the receive pair.
MDI[0]± should be tied to ground if not used.
