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.
