8.3.2.1 Magic Packet Structure
When configured for Magic Packet detection, the DP83822 scans all incoming frames addressed to the node for a specific data sequence. This sequence identifies the frame as a Magic Packet frame.
A Magic Packet frame must also meet the basic requirements for the LAN technology chosen, such as SOURCE ADDRESS, DESTINATION ADDRESS (which may be the receiving station’s IEEE address or a BROADCAST ADDRESS), and CRC.
The specific Magic Packet sequence consists of 16 duplications of the MAC address of this node, with no breaks or interruptions, followed by Secure-ON password if security is enabled. This sequence can be located anywhere within the packet, but must be preceded by a synchronization stream. The synchronization stream is defined as 6-bytes of 0xFF.
