5
Autonegotiation Complete
1
Autonegotiation process completed.
0
Autonegotiation process not com-
pleted.
If autonegotiation is enabled, this bit indi-
cates whether the autonegotiation process
has been completed.
1
Remote fault detected.
0
Remote fault not detected.
This bit is latched to 1 if the RF bit in the
autonegotiation link partner ability register
(bit 13, register address 05h) is set or the
receive channel meets the far-end fault
indication function criteria. It is unlatched
when this register is read.
1
Capable of autonegotiation.
0
Not capable of autonegotiation.
This bit defaults to 1, indicating that the
LU3X31FT is capable of autonegotiation.
1
Link is up.
0
Link is down.
This bit reflects the current state of the link-
test-fail state machine. Loss of a valid link
causes a 0 latched into this bit. It remains 0
until this register is read by the serial man-
agement interface.
1
Jabber condition detected.
0
Jabber condition not detected.
During 10Base-T operation, this bit indi-
cates the occurrence of a jabber condition.
It is implemented with a latching function
so that it becomes set until it is cleared by
a read.
1
Extended register set.
0
No extended register set.
This bit defaults to 1, indicating that the
LU3X31FT implements extended registers.
