Resolved Speed
The values are updated after the completion of Auto-
Negotiation. The registers retain their values during soft-
ware reset. This bit is valid only after the resolved bit 11
is set.
0 = 10 Mbps
1 = 100 Mbps.
Resolved Duplex Mode
The values are updated after the completion of Auto-
Negotiation. The registers retain their values during soft-
ware reset. This bit is valid only after the resolved bit 11
is set.
0 = Half-duplex
1 = Full-duplex
Page Receive Mode
0 = Page not received
1 = Page received
Speed and Duplex Resolved. Speed and duplex bits (14
and 13) are valid only after the Resolved bit is set. The
Resolved bit is set when Auto-Negotiation has resolved
the highest common capabilities or Auto-Negotiation is
disabled.
0 = Not resolved
1 = Resolved
Link (real time)
0 = Link down
1 = Link up
Always 000.
MDI/MDIX Crossover Status
0 = Transmit on pins TXP/TXN, Receive on pins RXP/
1 = Transmit on pins RXP/RXN, Receive on pins TXP/
Always 0.
Energy Detect Status
0 = Chip is not in sleep mode (Active)
1 = Chip is in sleep mode (No wire activity)
