0x0
RO
Vct_result
VCT result.
[00] = normal condition.
[01] = open condition has been detected in the
cable.

Vct_en
VCT enable.
1 = the cable diagnostic test is enabled. It is self-
cleared after the VCT test is done.
0 = it indicates the cable diagnostic test is
completed and the status information is valid for
read
