Wake-Up Frame Filter (WFF)
The Wake-up frame filter is configured through this register using an
indexing mechanism. After power-on reset, digital reset, or soft reset, the
Host MAC loads the first value written to this location to the first DWORD in
the Wake-up frame filter (filter 0 byte mask). The second value written to this
location is loaded to the second DWORD in the wake-up frame filter (filter 1
byte mask) and so on. Once all eight DWORD’s 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.

Note:

This is a write-only register.
