R2
Parity Upper DWORD is an even parity bit that protects
AD[64:32] and C/BE[7:4]. PAR64 must be valid one
clock after each address phase on any transaction in which
REQ64B is asserted.

Serial data clock
EEDI/AUX
EEDI: Serial data input
AUX: Input pin to detect if Aux. Power exists or not on initial
power-on.
This pin should be connected to EEPROM. To support wakeup
from ACPI D3cold or APM power-down, this pin must be pulled
high to aux. power via a resistor. If this pin is not pulled high to
Aux. Power, the RTL8110S assumes that no Aux. Power exists.

C2
In MDI mode, this is the first pair in 1000Base-T, i.e. the
BI_DA+/- pair, and is the transmit pair in 10Base-T and
100Base-TX.
In MDI crossover mode, this pair acts as the BI_DB+/- pair,
and is the receive pair in 10Base-T and 100Base-TX.
