Addr Name Description Access HW Reset
Value
•
Bit [9]: RESTART_AUTO_NEGOTIATION. Set this bit
to 1 to restart auto-negotiation.
The PHY clears the bit as soon as auto-negotiation is
restarted.

status
•
Bit [5]: AUTO_NEGOTIATION_COMPLETE. A value of
"1" indicates that the auto-negotiation is completed.
RO 0
•
Bit [3]: AUTO_NEGOTIATION_ABILITY. A value of
"1" indicates that the PCS function supports auto-
negotiation.
RO 1
•
Bit [2]: LINK_STATUS. A value of "0" indicates that
the link is lost. Value of 1 indicates that the link is
established.
