Description
Vct 10M short
Less than 10 meter short
Vct result
[00] = normal condition
[01] = open condition has been detected in cable
[10] = short condition has been detected in cable
[11] = cable diagnostic test is failed
Vct enable
1 = the cable diagnostic test is enabled. It’ll be self-
cleared after VCT test is done
0 = it indicates the cable diagnostic test is completed
and the status information is valid for read
Force Link
1 = Force link pass
0 = Normal Operation
Power Saving
1 = Disable
0 = Enable power saving
Remote loop back >>
1 = Loop back at PMD/PMA of port 2’s PHY
End: TXP2/TXM2 (port 2)
0 = normal operation.
VCT fault count
Distance to the fault. It’s approximately
0.4m*vct_fault_count
Description
LED off
1 = Turn off all port 2’s LEDs (LED2_3, LED2_2,
LED2_1, LED2_0. These pin/balls will be driven high
if this bit is set to one.
0 = normal operation
Txids
1 = disable port’s transmitter
0 = normal operation
Restart AN
1 = restart auto-negotiation
0 = normal operation
Disable Far end fault
1 = disable far end fault detection & pattern
transmission.
0 = enable far end fault detection & pattern
transmission.
