At the timing of the interruption power-off to power-on, there when the voltage of the part of the power supply does not fall, There is some problem?

 

Please refer attachment Fig.

 

The specification VDD_SNVS_IN after the other power supply on.

As shown in attachment Figure widened voltage of 1.8 v and 3.3 v systems in the VDD_SNVS_IN injection timing.

Is this problem?

How voltage down of 1.8v and 3.3v ?

Also Is there such threshold of spec?
