Description
EESK O 111 A11 Serial data clock
EEDI/AUX I 109 B11 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 Boot PROM. 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 RTL8169S assumes that no Aux. Power exists.
EEDO O 108 A12 Serial data output
EECS/BRO
MCSB
O 106 B12 EECS: EEPROM chip select
BROMCSB: This is the chip select signal of the Boot PROM.

Description
MDI[0]+ I/O 1 C2
MDI[0]− I/O 2 D1
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.
MDI[1]+ I/O 5 D2
MDI[1]− I/O 6 E1
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.
MDI[2]+ I/O 14 F1
MDI[2]− I/O 15 G2
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.
MDI[3]+ I/O 18 G1
MDI[3]− I/O 19 H2
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.
