hi：

Can S32K144 internal RTC wake up itself in VLPR or VLPS mode?

What's the meaning of "The wakeup pin is not available for RTC on this device"?

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
