Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
100BASE-TX Full-Duplex Mode
When set, indicates that the PHY is capable of supporting 100BASE-TX
Full-Duplex mode.
100BASE-TX Half-Duplex Mode
When set, indicates that the PHY is capable of supporting 100BASE-TX
Half-Duplex mode.
10BASE-T Full-Duplex Mode
When set, indicates that the PHY is capable of 10BASE-T Full-Duplex
mode.
10BASE-T Half-Duplex Mode
When set, indicates that the PHY is capable of supporting 10BASE-T
Half-Duplex mode.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Management Frames with Preamble Suppressed
When set, indicates that the Management Interface is capable of
receiving management frames with the preamble suppressed.
Auto-Negotiation Complete
When set, indicates that the Auto-Negotiation process has been
completed and that the extended registers defined by the
Auto-Negotiation protocol are valid.
Remote Fault
When set, indicates that a remote fault condition has been detected.
This bit remains set until it is read, even if the condition no longer exists.
