Table 84.
There are 128 mask entries. The flexible filter mask and table is used to store the four
1-bit masks for each of the first 128 data bytes in a packet, one for each flexible filter.
If the mask bit is one, the corresponding flexible filter compares the incoming data byte
at the index of the mask bit to the data byte stored in the flexible filter value table.
Before writing to the flexible filter mask table the software device driver must first
disable the flexible filters by writing zeros to the Flexible Filter Enable bits of the WUFC
register (WUFC.FLXn).

All reserved fields read as zeros and are ignored on writes.
There are four flexible filters lengths. The flexible filter length table stores the minimum
packet lengths required to pass each of the flexible filters. Any packets that are shorter
than the programmed length won’t pass that filter. Each flexible filter considers a
packet that doesn’t have any mismatches up to that point to have passed the flexible
filter when it reaches the required length. It does not check any bytes past that point.
Before writing to the flexible filter length table the software device driver must first
disable the flexible filters by writing zeros to the Flexible Filter Enable bits of the WUFC
register (WUFC.FLXn).
