Hi NXP,
My device is S32G-VNP-RDB3. I have a question that I would like you to answer.
If i do not disable the PMIC watchdog when my device in STANDBY mode, what will happen on my device, reset or nothing?. Whether it is necessary to disable the watchdog before entering low power mode.
Hi @LIU_HAO,
It depends on the configuration of the PMIC (if applicable), in your case you can review the AN12952: S32Gx Power Saving Techniques Application Note there is mentioned at the chapter 4.3 Standby mode entry processes, that you need to configure the PMIC's Standby Window Counter prior to the Standby entry to make it start counting for this particular case of the S32G-VNP-RDB3 that use the VR5510.
If this configuration is not done the device will reset.

Also, you can review the demo: S32G: M kernel Standby demo and how to porting to Mcal
Let me know if you have any question.
