Remote fault 0, RO/LH Remote Fault
1 = Remote fault condition detected (cleared on read or by a
chip reset). Fault criteria and detection method is DM9010
implementation specific. This bit will set after the RF bit in
the ANLPAR (bit 13, register address 05) is set
0 = No remote fault condition detected

Link status
0,RO/LL Link Status
1 = Valid link is established (for either 10Mbps or 100Mbps
operation)
0 = Link is not established
The link status bit is implemented with a latching function, so
that the occurrence of a link failure condition causes the link
status bit to be cleared and remain cleared until it is read via
the management interface

Jabber detect 0, RO/LH Jabber Detect
1 = Jabber condition detected
0 = No jabber
This bit is implemented with a latching function. Jabber
conditions will set this bit unless it is cleared by a read to this
register through a management interface or a DM9010 reset.
This bit works only in 10Mbps mode
