SNLS614A September 2018 – December 2018 DP83869HM
Wake-on-LAN provides a mechanism to detect specific frames and notify the connected MAC through either a register status change, GPIO indication, or an interrupt flag. The WoL feature within the DP83869HM allows for connected devices placed above the Physical Layer to remain in a low power state until frames with the qualifying credentials are detected. Supported WoL frame types include: Magic Packet, Magic Packet with SecureOn, and Custom Pattern Match. When a qualifying WoL frame is received, the DP83869HM WoL logic circuit is able to generate a user-defined event (either pulses or level change) through any of the GPIO pins or a status interrupt flag to inform a connected controller that a wake event has occurred.
The Wake-on-LAN feature includes the following functionality:
In addition to the basic magic packet support, the DP83869HM also supports:
