10.10 Magic Packet Collection Filter
The Magic Packet filter scans all packet contents for a
Magic Packet pattern for the local MAC address. If a
valid Magic Packet pattern is found, then the frame will
be accepted. The Magic Packet pattern consists of a
sync pattern of six FFh bytes, followed by the MAC
address of the station the Magic Packet is intended for,
repeated 16 times. See Figure 10-2 for a sample Magic
Packet. This pattern may be located anywhere within
the packet. Other fields in the packet, such as the
destination address or bytes preceding or following the
Magic Packet pattern, are ignored.
This filter is disabled at power-up. To enable this filter,
set MPEN (ERXFCON<14>). If the filter is disabled or
the received packet is not a Magic Packet, the frame
will be passed to the next lower priority filter.
