I
LAN I/F Clock: This signal is driven by the Platform LAN Connect
component. The frequency range is 5 MHz to 50 MHz.
Received Data: The Platform LAN Connect component uses these
I signals to transfer data and control information to the integrated LAN
controller. These signals have integrated weak pull-up resistors.
Transmit Data: The integrated LAN controller uses these signals to
O transfer data and control information to the Platform LAN Connect
component.
O
LAN Reset/Sync: The Platform LAN Connect component’s Reset and
Sync signals are multiplexed onto this pin.

EEPROM Shift Clock: This signal is the serial shift clock output to the
EEPROM.
I
EEPROM Data In: This signal transfers data from the EEPROM to the
Intel^® ICH7. This signal has an integrated pull-up resistor.
O
EEPROM Data Out: This signal transfers data from the ICH7 to the
EEPROM.
O EEPROM Chip Select: This is the chip select signal to the EEPROM.
