Hi,all

I use the demo:Example_S32K144_RTC_VLPS_S32DS_ARM_22_v2, it is used to test VLPS function,but when I debug it, it will not enter the VLPS mode, I check the SMC_PMSTAT，it is still in RUN mode.

Then I debug the project, SMC_PMCTRL can not change, it is not in VLPS. I put led in board, exit the debug, restart the board,it still no work.

I use the S32K144 EVB-Q100 board, can someone tell me how to enter the VLPS mode?
