Note: The Auto-Negotiation states and error types are described in Clause 28 of IEEE 802.3.

Bit 7:

LGCILF: Link Good Check Incompatible Link Failure

0: Normal operation.

1: Auto-negotiation failed due to an incompatible link.

Bit 6:

LGCLSF: Link Good Check Line Status Failure

0: Normal operation.

1. Auto-negotiation failed due to a link fault.

Bit 5:

AKDLF: Acknowledge Detect Link Failure

0: Normal operation.

1: Auto-negotiation failed due to lack of reception of fast link pulses.

Bit 4:

AKDAMF: Acknowledge Detect Acknowledge Match Failure

0: Normal operation.

1: Auto-negotiation failed due to reception of a link code word with the ACK bit cleared.

Bit 3:

AKDCMF: Acknowledge Detect Consistency Match Failure

0: Normal operation.

1: Auto-negotiation failed due to reception of inconsistent link code words.

Bit 2:

ABDLF: Ability Detect Link Failure

0: Normal operation.

1: Auto-negotiation failed due to lack of reception of fast link pulses.

Bit 1:

ABDAKMF: Ability Detect Acknowledge Match Failure

0: Normal operation.

1: Auto-negotiation failed due to the reception of link code word(s) with the ACK bit set.

Bit 0:

ABDABMF: Ability Detect Ability Match Failure

0: Normal operation.

1: Auto-negotiation failed due to the lack of reception of three consecutive link code words.
