Description
Writing a “1” will signal the link partner that a next page of
information is available to be sent after the base page during
autonegotiation.
0 = normal operation.
See IEEE 802.3 clause 37. Section 37.2.1.7
Read will return 0, writes will be ignored
00 = No Error (Link OK)
01 = Offline
10 = Link Failure
11 = Auto-Negotiation Error
See IEEE 802.3 clause 37. Section 37.2.1.5
Read will return 0, writes will be ignored
0001 = Full Duplex
See IEEE 802.3 clause 37. Sections 37.2.1.2 to 37.2.1.4
Read will return 0, writes will be ignored

(1) In SGMII mode, values written to the Autonegotiation Advertisement Register (0x04) will not be used to configure the functions of the
local device. Instead, 16'h40001 value is advertised as the ability of the local device per the SGMII specification.

Description
A “1” will indicate that the link partner has information for a next page at
autonegotiation.
0 = LP has no information for a next page
See IEEE 802.3 clause 37. Section 37.2.1.7
1 = Indicates that the link partner has successfully received a base or next
page
0 = Link partner has not received a base or next page
See IEEE 802.3 clause 37. Section 37.2.1.6
00 = No Error (Link OK)
01 = Offline
10 = Link Failure
11 = Auto-Negotiation Error
See IEEE 802.3 clause 37. Section 37.2.1.5
Reading these three bits will reflect the Base page ability bits sent by the
link partner through rx_config.
0001 = Full Duplex
See IEEE 802.3 clause 37. Sections 37.2.1.2 to 37.2.1.4
Reading these five bits will reflect the Base page ability bits sent by the
link partner through rx_config.
