Description
Vct_10m_short
1 = Less than 10 meter short.
Vct_result
VCT result.
[00] = normal condition.
[01] = open condition has been detected in the
cable.
[10] = short condition has been detected in the
cable.
[11] = cable diagnostic test has failed.
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
Force_lnk
Force link.
1 = force link pass.
0 = normal operation.
Pwrsave
Power-saving.
1 = disable power saving.
0 = enable power saving.
Remote (Near-End) Loopback (rlb)
1 = perform remote loopback at Port 2's PHY
(RXP2/RXM2 -> TXP2/TXM2, see Figure 16)
0 = normal operation
Vct_fault_count
VCT fault count.
The distance to the fault is approximately
0.4m*vct_fault_count.
