VR5510 ABIST2 SVS

[zeyu_yan]

Hi,

        for ASIL D ECU，if the SVS function of VR5510 is disable, should VR5510 enable the funciton of ABIST2?(since the voltages of PMIC do not change  )

I understand that it will have no affect on ABIST2 if SVS is configured or not.

But if SVS is not configured, what is the meaning to enable ABIST2 while ABIST1 has already covered and checked the voltage error that ABIST2 do?

You can see the datasheet page20---8.14 Application flow charts,no affect on ABIST2.
