The CS8952 does not support 100BASE-T4 opera-
tion, so this bit will always read 0.
When this bit is set, it indicates that the CS8952 is
capable of 100BASE-TX Full-Duplex operation. This
bit reflects the status of the 100BASE-TX/Full-Duplex
bit in the Auto-Negotiation Advertisement Register
(address 04h).
When this bit is set, it indicates that the CS8952 is
capable of 100BASE-TX Half-Duplex operation. This
bit reflects the status of the 100BASE-TX/Half
Duplex bit in the Auto-Negotiation Advertisement
Register (address 04h).
When this bit is set, it indicates that the CS8952 is
capable of 10BASE-T Full-Duplex operation. This bit
reflects the status of the 10BASE-T/Full Duplex bit in
the Auto-Negotiation Advertisement Register
(address 04h).
When this bit is set, it indicates that the CS8952 is
capable of 10BASE-T Half-Duplex operation. This bit
reflects the status of the 10BASE-T/Half Duplex bit in
the Auto-Negotiation Advertisement Register
(address 04h).
When set, this bit indicates that the CS8952 is capa-
ble of accepting management frames regardless of
whether they are preceded by the preamble pattern.
When clear, it indicates that the management frame
must be preceded by the preamble pattern to be con-
sidered valid. This bit reflects the status of the MR
Preamble Enable bit in the PCS Sub-Layer Configu-
ration Register (address 17h).
This bit is set to a 1 when the auto-negotiation pro-
cess has completed. This is an indication that data is
valid in the Auto-Negotiation Advertisement Register
(address 04h), the Auto-Negotiation Link Partner
Ability Register (address 05h), and the Auto-Negotia-
tion Expansion Register (address 06h).
When auto-negotiation is enabled, this bit is set if the
Remote Fault bit is set in the Auto-Negotiation Link
Partner Ability Register (address 05h). When auto-
negotiation is disabled, this bit will be set when a Far-
End Fault Indication for 100BASE-TX is detected.
