Hi,
The RTC module doesn’t wake up from VLPS, only from STOP1/2 modes. And it is functional in VLPR.
Please refer to Chapter 7.3.1 (Wake-up sources) and Table 35-4 (Module operation in available low power modes).
The wakeup pin is asserted when a RTC interrupt occurs.
But this pin is not available on S32K1xx.
Regards,
Daniel
