1
RO
AN page received
When set to 1, a page has been received. When 0, a
page has not been received. The current value
clears when the register is read. For more informa‐
tion, refer to 7.1.6 in Clause 73.8 of IEEE 802.3ap-
2007.
2
RO
AN Complete
When asserted, Auto-Negotiation has completed.
When 0, Auto Negotiation is in progress. For more
information, refer to 7.1.5 in Clause 73.8 of IEEE
802.3ap-2007.
3
RO
AN ADV Remote Fault
When set to 1, fault information has been sent to
the link partner. When 0, a fault has not occurred.
The current value clears when the register is read.
Remote Fault (RF) is encoded in bit D13 of the
base Link Codeword. For more information, refer
to Clause 73.6.7 of and 7.16.13 of IEEE
802.3ap
-
2007.
4
RO
AN RX SM Idle
When set to 1, the Auto-Negotiation state machine
is in the idle state. Incoming data is not Clause 73
compatible. When 0, the Auto-Negotiation is in
progress.
5
RO
AN Ability
When set to 1, the transceiver PHY is able to
perform Auto Negotiation. When set to 0, the
transceiver PHY i s not able to perform Auto
Negotiation. If your variant includes Auto Negotia‐
tion, this bit is tied to 1. For more information,
refer to 7.1.3 and 7.48.0 of Clause 45 of IEEE
802.3ap-2007.
6
RO
AN Status
When set to 1, link is up. When 0, the link is down.
The current value clears when the register is read.
For more information, refer to 7.1.2 of Clause 45 of
IEEE 802.3ap-2007.
7
RO
LP AN Ability
When set to 1, the link partner is able to perform
Auto Negotiation. When 0, the link partner is not
able to perform Auto-Negotiation. For more
information, refer to 7.1.0 of Clause 45 of IEEE
802.3ap-2007.
