4.1.8.2. Magic Packet Detection

Magic packet detection wakes up a node that was put to sleep. The MAC function detects magic packets with any of the following destination addresses:
  • Any multicast address
  • A broadcast address
  • The primary MAC address configured in the mac_0 and mac_1 registers
  • Any of the supplementary MAC addresses configured in the following registers if they are enabled: smac_0_0, smac_0_1, smac_1_0, smac_1_1, smac_2_0, smac_2_1, smac_3_0 and smac_3_1

When the MAC function detects a magic packet, the WAKEUP bit in the command_config register is set to 1, and the etherStatsPkts and etherStatsOctets statistics registers are incremented.

Magic packet detection is disabled when the SLEEP bit in the command_config register is set to 0. Setting the SLEEP bit to 0 also resets the WAKEUP bit to 0 and resumes the transmit and receive operations.
