PIC18F97J60 FAMILY
18.8.6 MAGIC PACKET FILTER
The Magic Packet pattern consists of a sync pattern of
six FFh bytes, followed by 16 repeats of the destination
address (Figure 18-14). The Magic Packet filter checks
the destination address and data fields of all incoming
packets. If the destination address matches the
MAADR registers and the data field holds a valid Magic
Packet pattern someplace within it, then the packet will
meet the Magic Packet filter criteria.
