Description
1 = Less than 10 meter short
00 = Normal condition
01 = Open condition detected in cable
10 = Short condition detected in cable
11 = Cable diagnostic test has failed
1 = Enable cable diagnostic test. 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.
1 = Force link pass
0 = Normal Operation
0 = Enable power saving
1 = Disable power saving
1 = Perform Remote loopback, as follows:
0 = Normal Operation
Bit[8] of VCT fault count
Distance to the fault.
It’s approximately 0.4m*vct_fault_count[8:0]
Description
Bits[7:0] of VCT fault count
Distance to the fault.
It’s approximately 0.4m*Vct_fault_count[8:0]
