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
Reserved
Do not change the default value.
=1, Perform Remote loopback, as follows:
=0, Normal Operation
