Description
HL[11:0]
I/O
Hub Interface Signals
HL_STB
I/O
Hub Interface Strobe: One of two differential strobe signals used to transmit and
receive data through the hub interface.
HL_STB#
I/O
Hub Interface Strobe Complement: Second of the two differential strobe signals.
HLCOMP
I/O
Hub Interface Compensation: Used for hub interface buffer compensation.

Name
Type
Description
LAN0_CLK
LAN1_CLK
I
LAN Interface Clock:
This signal is driven by the LAN Connect component. The
frequency range is 0.8 MHz to 50 MHz.
LAN0_RSTSYNC
LAN1_RSTSYNC
O
LAN Reset/Sync:
The LAN Connect component’s Reset and Sync signals are
multiplexed onto this pin.
LAN0_RXD[2:0]
LAN1_RXD[2:0]
I
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.
LAN0_TXD[2:0]
LAN1_TXD[2:0]
O
Transmit Data
: The integrated LAN Controller uses these signals to transfer
data and control information to the LAN Connect component.

Type
Description
EE0_CS
EE1_CS
O
EEPROM Chip Select:
These signals are chip-select signals to the EEPROMs.
EE0_DIN
EE1_DIN
I
EEPROM Data In:
These signals transfer data from the EEPROMs to the 82801E
C-ICH. These signals have an integrated pull-up resistor.
EE0_DOUT
EE1_DOUT
O
EEPROM Data Out:
These signals transfer data from the 82801E C-ICH to the
EEPROMs.
EE0_SHCLK
EE1_SHCLK
O
EEPROM Shift Clock:
These signals are the serial shift clock output to the
EEPROMs.
