Description
Organizationally Unique Identifier.
The third through the twenty-fourth bit
of the OUI assigned to the PHY manufacturer by the IEEEare to be placed
in bits [2.15:0] and [3.15:10]. The value for bits 15:0 is 0180h.
Organizationally Unique Identifier.
The remaining 6 bits of the OUI. The
value for bits 15:10 is 1Dh.
Model Number.
6-bit model number of the device. The model number is
54 DEC.
Revision Number.
The value of the present revision number. The value is
01h for the first version.

R/W
Next Page.
The next-page function is activated by setting this bit to a 1.
This will allow the exchange of additional data. Data is carried by optional
next pages of information.
Acknowledge.
This bit is the acknowledge bit from the link code word.
Remote Fault.
When set to 1, the LU3X54FT indicates to the link partner a
remote fault condition.
Reserved.
These bits will read 0.
Pause.
When set to a 1, it indicates that the LU3X54FT wishes to
exchange flow control information with its link partner.
100Base-T4.
This bit should always be set to 0.
100Base-TX Full Duplex.
If written to 1, autonegotiation will advertise that
the LU3X54FT is capable of 100Base-TX full-duplex operation.
100Base-TX.
If written to 1, autonegotiation will advertise that the
LU3X54FT is capable of 100Base-TX operation.
10Base-T Full Duplex.
If written to 1, autonegotiation will advertise that
the LU3X54FT is capable of 10Base-T full-duplex operation.
10Base-T.
If written to 1, autonegotiation will advertise that the LU3X54FT
is capable of 10Base-T operation.
