ANEGF
R,0,RC
AUTO-NEGOTIATION FAIL: This bit is set when auto-negotiation
completes and no common technology was found. It remains set until
read.
18.11
DPLX
R, 0
DUPLEX: This bit indicates the result of the auto-negotiation for duplex
arbitration. If set it indicates that full-duplex was the highest common
denominator. If clear it indicates that half-duplex was the highest
common denominator.
18.10
RATE
R, 0
RATE: This bit indicates the result of the auto-negotiation for data rate
arbitration. If set it indicates that 100BASE-TX was the highest common
denominator. If clear it indicates that 10BASE-T was the highest
common denominator.
18.9
RX-PASS
R, 0
RECEIVE PASS: In 10BASE-T mode, this bit indicates that Manchester
data has been detected. In 100BASE-TX mode, it indicates that a valid
received

RX-LOCK
R, 0
RECEIVE LOCK: Indicates that the receive PLL has locked onto the
received signal for the selected speed of operation (10BASE-T or
100BASE-TX). This bit is cleared whenever a cycle-slip occurs, and
will remain cleared until it is read.
