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?
