Introduction
The Wake on LAN (WoL) is a feature that allows a load/client on a network to be turned on by a message sent via
the network. The idea behind WoL is that devices on the network will consume less power in stand-by mode and
only “wake up” when required, thus making the system green or environmentally friendly. Having a separate network
monitor that scans network packets to look for special data sequences is required under such conditions. This
reference design implements the portion that scans network packets for a special data sequence and transmits an
interrupt signal to the system controller.
