Jabber Detect: This bit only has meaning in 10 Mb/s mode
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.
Duplex:
This bit indicates duplex status and is determined from Auto-Nego-
tiation or Forced Modes.
1 = Full duplex mode.
0 = Half duplex mode.
Note: This bit is only valid if Auto-Negotiation is enabled and com-
plete and there is a valid link or if Auto-Negotiation is disabled and
there is a valid link.
Speed10:
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 com-
plete 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 regis-
ter.
1 = Valid link established (for either 10 or 100 Mb/s operation)
0 = Link not established.
