1 = Remote Fault condition detected (cleared on read of BMSR (address 0x84) register or by reset). Fault
criteria: notification from Link Partner of Remote Fault via Auto-Negotiation
0 = No remote fault condition detected
This bit is a duplicate of the Jabber Detect bit in the BMSR register, except that it is not cleared upon a
read of the PHYSTS register.
1 = Jabber condition detected
0 = No Jabber
Auto-Negotiation Complete:
1 = Auto-Negotiation complete
0 = Auto-Negotiation not complete
Loopback:
1 = Loopback enabled
0 = Normal operation
This bit indicates duplex status and is determined from Auto-Negotiation or Forced Modes.
1 = Full duplex mode
0 = Half duplex mode
Note: This bit is only valid if Auto-Negotiation is enabled and complete and there is a valid link or if Auto-
Negotiation is disabled and there is a valid link.
This bit indicates the status of the speed and is determined from Auto-Negotiation or Forced Modes.
1 = 10 Mb/s mode
0 = 100 Mb/s mode
Note: This bit is only valid if Auto-Negotiation is enabled and complete and there is a valid link or if Auto-
Negotiation is disabled and there is a valid link.
Link Status:
This bit is a duplicate of the Link Status bit in the BMSR register, except that it will not be cleared upon a
read of the PHYSTS register.
1 = Valid link established (for either 10 or 100 Mb/s operation)
0 = Link not established
