Auto-Negotiation Fail Indication
This bit is set when auto-negotiation completes and no
common technology was found. It remains set until read.
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
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
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).
8
RXLCK
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).
