LAN Connect Interface
The 82562ET supports the LAN connect interface as specified in the LAN Connect Interface
Specification. The LAN Connect is the I/O Control Hub 2 (ICH2) interface to the 82562ET. The 8-
pin interface incorporates all MII and MII management functionality and includes the reset
functionality as well.
LAN Connect Clock
The 82562ET drives a 50 MHz or 5 MHz clock to the MAC depending on the selected technology
(100BASE-TX or 10BASE-T, respectively). The 82562ET does not stop the LAN Connect clock
for any reason. During reduced power mode, the 82562ET drives a 5 MHz clock.
LAN Connect Reset
To determine the type of signal on the PLC Reset/Synchronization pin, the 82562ET filters out
pulses that are less than 200 nanoseconds. To reset the 82562ET, the pulse should be longer than
500 µseconds.

Function
The driver blinks at a rate related to the utilization. The blinking occurs during
transmission or reception of a frame.
The driver is low for 100BASE-TX operation and high for 10BASE-T mode.
The driver is low when a valid link is present.
