When set to 1, enables Auto Negotiation function. The default
AN enable
value is 1. For additional information, refer to 7.0.12 in
Clause 73.8 Management Register Requirements, of IEEE
802.3ap-2007.
When set to 1, the user base pages are enabled. You can
AN base pages ctrl
send any arbitrary data via the user base page low/high bits.
When set to 0, the user base pages are disabled and the state
machine generates the base pages to send.
When set to 1, the user next pages are enabled. You can send
AN next pages ctrl
any arbitrary data via the user next page low/high bits. When
set to 0, the user next pages are disabled. The state machine
generates the null message to send as next pages.
When set to 1, the local device signals Remote Faults in the
Local device remote
Auto Negotiation pages. When set to 0, a fault has not
fault
occurred.
When set to 1, forces the TX nonce value to support some
Force TX nonce value
UNH testing modes. When set to 0, this is normal operation.
When set to 1, overrides the
Override AN
Parameters Enable AN_PAUSE
You must reset the Sequencer to reconfigure and restart into
Auto Negotiation mode. When set to 0, this is normal
operation and is used with 0x4B0 bit 0 and 0x4C3
bits[30:16].
When set to 1, resets all the 10GBASE-KR Auto Negotiation
Reset AN
state machines. This bit is self-clearing.
When set to 1, restarts the 10GBASE-KR TX state machine.
Restart AN TX SM
This bit self clears. This bit is active only when the TX state
machine is in the Auto Negotiation state. For more
information, refer to 7.0.9 in Clause 73.8 Management
Register Requirements of IEEE 802.3ap-2007.
When asserted, new next page info is ready to send. The data
AN Next Page
is in the XNP TX registers. When 0, the TX interface sends
null pages. This bit self clears. Next Page (NP) is encoded in
bit D15 of Link Codeword. For more information, refer to
Clause 73.6.9 and 7.16.15 of Clause 45.2.7.6 of IEEE
802.3ap-2007.
When set to 1, a page has been received. When 0, a page has
AN page received
not been received. The current value clears when the register
is read. For more information, refer to 7.1.6 in Clause 73.8 of
IEEE 802.3ap-2007.
When asserted, Auto-Negotiation has completed. When 0,
AN Complete
Auto Negotiation is in progress. For more information, refer to
7.1.5 in Clause 73.8 of IEEE 802.3ap-2007.
When set to 1, fault information has been sent to the link
AN ADV Remote Fault
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.
When set to 1, the Auto-Negotiation state machine is in the
AN RX SM Idle
idle state. Incoming data is not Clause 73 compatible. When
0, the Auto-Negotiation is in progress.
