82577 GbE PHY—Programmer’s Visible State
This bit indicates that the PHY is in standby
mode and is ready to perform IP phone
detection or TDR cable diagnostics. The PHY
enters standby mode when LNK_EN is
cleared (Register 23, bit 13 = 0b) and exits
standby mode and attempts to auto-
negotiate a link when LNK-EN is set (Register
23, bit 13 = 1b).
1b = PHY in standby mode.
0b = PHY not in standby mode.
11b = Reserved.
10b = Master/slave auto-negotiation fault.
01b = Parallel detect auto-negotiation fault.
00b = No auto-negotiation fault.
1b = Auto-negotiation complete.
0b = Auto-negotiation not complete.
1b = Pairs A and B swapped.
0b = Pairs A and B not swapped.
1b = Polarity inverted (10BASE-T only).
0b = Polarity normal (10BASE-T only).
11b = Undetermined.
10b = 1000BASE-T.
01b = 100BASE-TX.
00b = 10BASE-T.
1b = Full duplex.
0b = Half duplex.
1b = Link up.
0b = Link down.
1b = PHY transmitting a packet.
0b = PHY not transmitting a packet.
1b = PHY receiving a packet.
0b = PHY not receiving a packet.
1b = Collision occurring.
0b = Collision not occurring.
1b = Both partners have auto-negotiation
enabled.
0b = Both partners do not have auto-
negotiation enabled.
1b = Link partner advertised PAUSE.
0b = Link partner did not advertise PAUSE.
1b = Link partner advertised asymmetric
PAUSE.
0b = Link partner did not advertise
asymmetric PAUSE.
