PMCSR. This action will clear the WAKE event and clear the WAKE bit in the HIR and the PMEB primary
output, if it was enabled. If the HNR timer expires before the host clears the WAKE event then the QDR
bit for QUE5 is set triggering the transmission of the HNR frame contained in QUE5. The length of the
HNR timer is determined by the value contained in the Host Not Responding Count Register (HNRCR).
When configuring for Wake On LAN, the host should set the HNRCR with a value based on the longest
anticipated interrupt service latency.
OnNow Packets
The OnNow specification states that an OnNow compliant node must be able to wake up upon the
reception of a frame that matches a reference frame with a byte mask applied. Table 32 contains the
rules on processing OnNow packets.

Magic Packets
A magic packet is defined to be a frame that contains a specific sequence of bytes anywhere in its USER
field. Table 33 contains the rules on checking for the sequence in a frame and waking the host if it finds a
magic packet.
