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]
