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 should be read sequentially to
obtain the values stored in the WFF.
Note:
Wakeup Frame Filter (WUFF)
This register is used to configure the Wakeup Frame Filter.
Offset:
This register should be read and written using eight consecutive
DWORD operations. Failure 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.
