Example S32K324 STANDBY wake up using GPIO Switch DS3.5 RTD300

*******************************************************************************

 The purpose of this demo application is to present a usage of the
 POWER & WKUP IP Driver for the S32K3xx MCU.

In current example :--
SW-5 = PTB-26  -----> PRESS to enter the STANDBY mode.
SW-6 = PTB-19 = WKUP[38] --> PRESS to exit the STANDBY mode.

The example uses PIT-0 timer, to generate the periodic interrupt.

I tested on Our T172 EVB, with NPN external Ballast transistor is selected to supply the V15_MCU domain. I am able to wake up from standby mode.

If we select 2-3 in J31 then NPN external Ballast transistor is selected to supply the V15_MCU domain & wakeup is ok on T172 EVB

You have to make following settings in code :--
