Fault
1 -> A fault has been detected via the parallel detection
function (updated on read)
0 -> A fault has not been detected
1 -> Remote fault condition detected
0 -> No remote fault condition detected
Set when link partner signaled a remote fault condition (RN05 -
bit 13) or a far-end-fault indicator was asserted. Latched, so
the occurrence of a remote fault causes the remote fault bit to
become set and remain set until it is cleared (by register read,
if no more fault is present).
1 -> Link code word received (updated on read)
0 -> LCW not yet received
1 -> LP supports auto-negotiation (updated on read)
0 -> LP does not support auto-negotiation
1 -> Speed is 100 Mb/s
0 -> Speed is 10 Mb/s
Set by auto-negotiation 100BASE-TX link control
1 -> Link is up (10–100 Mb/s)
0 -> Link is down
This bit is cleared at link failure and set after a register read if a
valid link is established
1 -> Auto-negotiation enabled
0 -> Auto-negotiation disabled
Set by RN00[12], if RN11[10] is 0 (not FX-mode)
1 -> Jabber condition detected
0 -> No jabber condition detected.
Set at jabber condition detection, cleared only after register
read (if no more jabber condition is present).
Fixed to 0 in 100Base-X modes.
Same as RN01[1]
