Wake-Up Frame Filter (WFF). Wake-Up Frame Filter (WFF). The Wake-up frame filter is configured
through this register using an indexing mechanism. After hardware reset, or soft reset, the 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 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.
Note:
Reserved
Global Unicast Enable (GUE). When set, the MAC wakes up from power-saving mode on receipt of
a global unicast frame. A global unicast frame has the MAC Address [0] bit set to 0.
Reserved
Remote Wake-Up Frame Received (WUFR). The MAC, upon receiving a valid Remote Wake-up
frame, sets this bit.
Magic Packet Received (MPR). The MAC, upon receiving a valid Magic Packet, sets this bit.
Reserved
Wake-Up Frame enabled (WUEN). When set, Remote Wake-Up mode is enabled and the MAC is
capable of detecting wake-up frames as programmed in the wake-up frame filter.
Magic Packet Enable (MPEN). When set, Magic Packet Wake-up mode is enabled.
Reserved
WUFF—Wake-up Frame Filter
This register is used to configure the wake up frame filter.
WUCSR—Wake-up Control and Status Register
This register contains data pertaining to the MAC’s remote wake-up status and capabilities.
