Description
1 – Remote Fault detected
0 – Remote Fault not detected
This bit is latched to 1 if the RF bit in the auto negotiation
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 auto negotiation
0 – Not capable of auto negotiation
TP : This bit is set to 1 all the time, indicating that D7001 is
capable of auto negotiation.
FX : This bit is set to 0 all the time, indicating that D7001 is
not capable of auto negotiation in Fiber Mode.
Link Status
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
management interface. Whenever Linkup, this bit should be
read twice to get link up status
1 – Jabber condition detected
0 – Jabber condition not detected
1 – Extended register set
0 – No extended register set
This bit defaults to 1, indicating that the D7001 implements
extended registers.
