Hi Fakhrul,

Thanks for the review.

We have checked the above list and it is fulfilled.

Actually we have noticed that after failure there is success and so on : pass-fail-pass-fail-pass-fail...

The power is stable during the test.  A failing condition occurs before ALERT goes low.  It is always after a specific number of AVST Clocks; the process fails after 4130 AVST_CLK cycles.

nConfig/nStatus start ok .

I haven't read STATUS BYTE after nStatus went low because PMBus activity has not started yet.  Please suggest if this can lead to something.

Thanks,

Itzik
