Description
Jabber Interrupt Enable
Receive Error Interrupt Enable
Page Received Interrupt Enable
Parallel Detection Fault Interrupt Enable
Link Partner Acknowledge Interrupt Enable
Link Status Not OK Interrupt Enable
Remote Fault Interrupt Enable
Auto-Negotiation Complete Interrupt Enable
This bit is set when a jabber event is detected.
This bit is set when RX_ER transitions high.
This bit is set when a new page is received from link partner
during Auto-Negotiation.
This bit is set for a parallel detection fault.
This bit is set when an FLP with the acknowledge bit set is
received.
This bit is set when link status switches from OK status to Not-OK
(Fail or Ready).
This bit is set when a remote fault is detected.
This bit is set when Auto-Negotiation is complete.

Operating in 100BASE-X mode:
1 = A valid signal has been received but the PLL has not
necessarily locked.
0 = A valid signal has not been received.
Operating in 10BASE-T mode:
1 = Manchester data has been detected.
0 = Manchester data has not been detected.
1 = Receive PLL has locked onto received signal for selected
data-rate (10BASE-T or 100BASE-X).
0 = Receive PLL has not locked onto received signal.
This bit remains set until it is read.
Ignore when read.
