Hi
I am trying to use VPLS power mode in S32K148. And i want to wakeup through GPIO interrupt.
In my current design i am using Internal clock. I am not using any external crystal Oscillator in my design.
As mentioned in the notes of reference Manual Section "Module Operation in available power modes" that “ Device Can Support ASYNC Wakeup from VPLS through GPIO”
So in this case which clock would be active
Please refer the snapshot attached for detail.
Solved! Go to Solution.
You can refer the power_mode_switch_s32k148 example in S32SDK S32K1XX RTM 4.0.1.
Asynchronous Wake-up Interrupt Controller (AWIC) detect asynchronous wake-up events in stop modes and signal to clock control logic to resume system clocking.
Pin interrupts one of the VLPS wake-up sources.
There is not much information about the AWIC module in our manual. But it mentioned: Full documentation for this module is provided by Arm and can be found at arm.com.
So I think consulting ARM may get more accurate answers.
Best Regards,
Robin

Hi @Robin_Shen
Thanks for your detailed response.
Question: While using internal clock (No external crystal oscillator), is it possible to wakeup from VPLS mode through GPIO interrupt?
Yes.
You can refer the power_mode_switch_s32k148 example in S32SDK S32K1XX RTM 4.0.1.
