Vct_result
VCT result.
[00] = normal condition.
[01] = open condition has been detected in cable.
[10] = short condition has been detected in cable.
[11] = cable diagnostic test is 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.
Reserved
Remote (Near-end) loopback (rlb)
1 = perform remote loopback at PHY
(RXP1/RXM1 -> TXP1/TXM1, see Figure 11)
0 = normal operation
Vct_fault_count
VCT fault count.
Distance to the fault. It’s approximately
0.4m*vct_fault_count.
Description
LED Off
1 = Turn off all of the port 1 LEDs (P1LED3, P1LED2,
P1LED1, P1LED0). These pins are driven high if this bit
is set to one.
0 = normal operation.
Txids
1 = disable the port’s transmitter.
0 = normal operation.
