EEPROM Chip Select: These signals are chip-select signals to the EEPROMs.
EEPROM Data In: These signals transfer data from the EEPROMs to the 82801E
C-ICH. These signals have an integrated pull-up resistor.
EEPROM Data Out: These signals transfer data from the 82801E C-ICH to the
EEPROMs.
EEPROM Shift Clock: These signals are the serial shift clock output to the
EEPROMs.
Hub Interface Signals
Hub Interface Strobe: One of two differential strobe signals used to transmit and
receive data through the hub interface.
Hub Interface Strobe Complement: Second of the two differential strobe signals.
Hub Interface Compensation: Used for hub interface buffer compensation.
LAN Interface Clock: This signal is driven by the LAN Connect component. The
frequency range is 0.8 MHz to 50 MHz.
LAN Reset/Sync: The LAN Connect component’s Reset and Sync signals are
multiplexed onto this pin.
Received Data: The LAN Connect component uses these 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 transfer
data and control information to the LAN Connect component.
