How can I get the wakeup resource In S32K142 after The chip exits Stop or VLPS Mode?

[Jinyuxin]

In my project of S32K142, There are some wakeup resources,such as Can、Pin interrupt、WDTG and so on，but How can I get the real wakeup resource after S32K142  is wakeuped?

Hello Daniel：

Thank you for your answer,at first.    

Must I put  the  getting wakeup resouce process in each ISR Function?

Can I put this processing after the calling of POWER_SYS_SetMode(VLPS, ..)?

Thank you.

Hi @Jinyuxin,

You need to identify the interrupt within the ISR.

This is not much of processing.
