Wakeup Frame Filter (WFF). The Wakeup Frame Filter is configured through this register using an
indexing mechanism. Following a reset, the MAC loads the first value written to this location to the
first DWORD in the Wakeup Frame Filter (filter 0 byte mask). The second value written to this location
is loaded to the second DWORD in the Wakeup Frame Filter (filter 1 byte mask) and so on. Once all
eight DWORDs have been written, the internal pointer will once again point to the first entry and the
filter entries can be modified in the same manner. Similarly, eight DWORDs can be read sequentially
to obtain the values stored in the WFF.
Note: This register should be read and written using eight consecutive DWORD operations. Failure
WUFF—Wakeup Frame Filter
This register is used to configure the wake up frame filter.

Default Value:
to read or write the entire contents of the WFF may cause the internal read/write pointers to
be left in a position other than pointing to the first entry. A mechanism for resetting the
internal pointers to the beginning of the WFF is available via the WFF Pointer Reset
(WFF_PTR_RST) bit of the
mechanism enables the application program to re-synchronize with the internal WFF pointers
if it has not previously read/written the complete contents of the WFF.
