Organizationally Unique Identifier. The third through the twenty-fourth
bit of the OUI assigned to the PHY manufacturer by the IEEE are to be
placed in bits. 2.15:0 and 3.15:10. This value is programmable.
Organizationally Unique Identifier. The remaining 6 bits of the OUI. The
value for bits 24:19 is programmable.
Model Number. 6-bit model number of the device. The model number is
programmable.
Revision Number. The value of the present revision number. The version
number is programmable.
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 PHY indicates to the link partner a remote
fault condition.
Pause. When set to a 1, it indicates that the PHY 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 PHY is capable of 100Base-TX full-duplex operation.
100Base-TX. If written to 1, autonegotiation will advertise that the PHY is
capable of 100Base-TX operation.
10Base-T Full Duplex. If written to 1, autonegotiation will advertise that
the PHY is capable of 10Base-T full-duplex operation.
10Base-T. If written to 1, autonegotiation will advertise that the PHY is
capable of 10Base-T operation.
Selector Field. Reset with the value 00001 for IEEE 802.3.
Link Partner Next Page. When this bit is set to 1, it indicates that the link
partner wishes to engage in next page exchange.
Link Partner Acknowledge. When this bit is set to 1, it indicates that the
link partner has successfully received at least three consecutive and
consistent FLP bursts.
Remote Fault. When this bit is set to 1, it indicates that the link partner has
a fault.
Technology Ability Field. This field contains the technology ability of the
link partner. These bits are similar to the bits defined for the MR4 register
(see Table 16).
Selector Field. This field contains the type of message sent by the link
partner. For IEEE 802.3 compliant link partners, this field should read
00001.
