Datasheet
Note: The wake-up event is supported only if the PME Enable bit in the Power Management Control/
The following tables list the functionality at the different power states for the 82551IT.
Wake-up Events
There are two types of wake-up events: “Interesting” Packets and Link Status Change. These two
events are detailed below.
Status (PMCSR) register is set.
“Interesting” Packet Event
In the power-down state, the 82551IT is capable of recognizing “interesting” packets. The 82551IT
supports pre-defined and programmable packets that can be defined as any of the following:
This allows the 82551IT to handle various packet types. In general, the 82551IT supports
programmable filtering of any packet in the first 128 bytes.
