Xon — WO. This bit should only be used if the LAN controller is configured to operate
with IEEE frame-based flow control.
0 = This bit always returns 0 on reads.
1 = Writing a 1 to this bit resets the Xoff request to the LAN controller, clearing bit 9 in
Reserved
Flow Control Threshold — R/W. The LAN controller can generate a Flow Control Pause
frame when its Receive FIFO is almost full. The value programmed into this field
determines the number of bytes still available in the Receive FIFO when the Pause
frame is generated.
Link Status Change Indication — R/WC.
0 = Software clears this bit by writing a 1 to it.
1 = The link status change bit is set following a change in link status.
Magic Packet — R/WC.
0 = Software clears this bit by writing a 1 to it.
1 = This bit is set when a Magic Packet is received regardless of the Magic Packet wake-
Interesting Packet — R/WC.
0 = Software clears this bit by writing a 1 to it.
1 = This bit is set when an “interesting” packet is received. Interesting packets are
