hi,

    i"m using the s32k142 with RUN mode and VLPS mode, through the GPIO interrupt to wake up the chip from VLPS mode, it's working fine in most of times,but there is a slight chance that can't wake up from VLPS mode,only reconnect the power can make chip normal.this situation happened in different boards and can't reproduce.

    I would like to know,what situation may cause the MCU can't wake up from VLPS mode? thank you very much.
