Hi Team,
Please tell me about register 0x001E bit[1](TDR process failed).
A customer executed TDR by enabling register 0x001E bit[15] with the link up status.
When they read register 0x001E, the result was 0x0003.
This means cable measurement process is complete and fail.
They executed TDR with the cable disconnected and the link down.
When they read register 0x001E, the result was 0x0002.
This means cable measurement process is complete and not fail.
Is the following my understanding correct?
=======================================
In the former case, the reflection peak value could not be obtained because the impedance is matched, so it was bit[1]=1(process failed).
That is, it can be determined that there is no problem with the cable.
In the latter case, the reflection peak value could be obtained because the impedance is mismatched, so it was bit[1]=0(process not failed).
If there is one peak, the user can find cable length by Reading register 0x0180 to 0x0184, especially 0x0180.
=======================================
Best Regards,
