MCU :S32K144

SDK : 0.8.6

I 'd like to ask a question about mcu wake up from vlps mode. 

Condition Description: 

I set power mode from HSRUN to RUN mode,then I set external pin interrupt of PTE.4,PTE.0,PTE.8. After all this complete,I set power mode from RUN to VLPS mode.

Question:

Is it possible to have an interruption of PTE.0/PTE.4/PTE.8, but not wake up from vlps mode?

Hi hehe haha

Answering your question; Yes, any enabled pin interrupt is capable of waking the system from VLPS. Have you tried the power_mode_switch example from the SDK 3.0.0? This demo is a fully functional demo.


Have a great day,
