Table 3. EEPROM
Description
Serial Data Clock.
EEDI: Output to serial data input pin of EEPROM.
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 RTL8111C
assumes that no Aux. Power exists.
Input from Serial Data Output Pin of EEPROM.
EECS: EEPROM chip select.

Table 4. Transceiver Interface
Description
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.
In MDI mode, this is the second pair in 1000Base-T, i.e., the BI_DB+/- pair, and
is the transmit pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DA+/- pair, and is the transmit
pair in 10Base-T and 100Base-TX.
In MDI mode, this is the third pair in 1000Base-T, i.e., the BI_DC+/- pair.
In MDI crossover mode, this pair acts as the BI_DD+/- pair.
In MDI mode, this is the fourth pair in 1000Base-T, i.e., the BI_DD+/- pair.
In MDI crossover mode, this pair acts as the BI_DC+/- pair.
