Description
Reserved
1 = polarity is reversed
0 = polarity is not reversed
1 = MDI-X
0 = MDI
1 = Force link pass
0 = Normal Operation
0 = Enable power saving
1 = Disable power saving
1 = Perform Remote loopback, as follows:
0 = Normal Operation
Reserved
Do not change the default value.
Description
1 = enable cable diagnostic. After VCT test has
completed, this bit will be self-cleared.
0 = indicate cable diagnostic test (if enabled) has
completed and the status information is valid for
read.
00 = normal condition
01 = open condition detected in cable
10 = short condition detected in cable
11 = cable diagnostic test has failed
1 = Less than 10 meter short
Reserved
Distance to the fault.
It’s approximately 0.4m*vct_fault_count[8:0]
