4.0 Register Set (Continued)

4.2.18 Wake Command/Status Register

The WCSR register is used to configure/control and monitor the DP83821 Wake On LAN logic. The Wake On LAN logic

is used to monitor the incoming packet stream while in a low-power state, and provide a wake event to the system if the

desired packet type, contents, or Link change are detected.
