MDC
Management Data Clock.
MDC is the management data clock reference. A continuous
clock is not expected. The maximum frequency supported is
12.5 MHz.

MDIO
I/O
Management Data Input Output.
MDIO transfers management data in and out of the device
synchronous to MDC. This pin should be connected to VDDO
through a 5.1-kΩ pull up resistor.

29,26,21,18, MDI[3:0]P,
30,27,22,19 MDI[3:0]M
Twisted- Pair Media Dependent Interface
In 1000BASE-T mode, all 4 pairs are both input and output at
the same time. In 100BASE-TX and 10BASE-T mode,
MDI[0]P/M are used for transmit pair under MDI configuration,
and is used for receive pair under MDIX configuration.
MDI[1]P/M are used for receive pair under MDI configuration,
and is used for transmit pair under MDIX configuration.
MDI[2]P/M and MDI[3]P/M are unused in 100BASE-TX and
10BASE-T mode.
