Auto-Negotiation Fail Indication: 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 Indication: This bit indicates the result of the
auto-negotiation for duplex arbitration as follows:
0 = Half-duplex was the highest common denominator
1 = Full-duplex was the highest common denominator
18.10
RATE
R
0
Rate Indication: This bit indicates the result of the auto-
negotiation for data rate arbitration as follows:
0 = 10Base-T was the highest common denominator
1 = 100Base-TX was the highest common denominator
18.9
RXSD
R
0
Receiver Signal Detect Indication: In 10Base-T mode, this
bit indicates that Manchester data has been detected. In
100Base-TX mode, it indicates that the receive signal
activity has been detected (but not necessarily locked on
to).
18.8
RX_LOCK
R
0
Receive PLL Lock Indication: Indicates that the Receive
PLL has locked onto the receive signal for the selected
speed of operation (10Base-T or 100Base-TX).
