Auto-Negotiation Fail Indication:
negotiation completes and no common technology was found. It
remains set until read.
Duplex Indication:
negotiation for duplex arbitration as follows:
Rate Indication: This bit indicates the result of the auto-negotiation
for data rate arbitration as follows:
Receiver Signal Detect Indication:
indicates that Manchester data has been detected. In 100Base-TX
mode, it indicates that the receive signal activity has been detected
(but not necessarily locked on to).
Receive PLL Lock Indication: Indicates that the Receive PLL has
locked onto the receive signal for the selected speed of operation
(10Base-T or 100Base-TX).
Reserved: Must set to ‘00h’.

0 : Half-duplex was the highest common denominator
1 : Full-duplex was the highest common denominator
0 : 10Base-T was the highest common denominator
1 : 100Base-TX was the highest common denominator
Link Partner Acknowledge Interrupt: This bit is set high by the
auto-negotiation logic when FLP bursts are received with the
acknowledge bit set.
Link Status Change Interrupt:
transitions from an OK status to a FAIL status.
Remote Fault Interrupt:
condition has been indicated by the link partner.
Auto-Negotiation Complete Interrupt: This bit is set by the auto-
negotiation logic upon successful completion of auto-negotiation.
This bit indicates the result of the auto-
