Wake the MCU from VLPS using a GPIO pin

Hello NXP team.

I am using the S32K144 microcontroller.

I want to wake up the MCU from VPLS using GPIO.

Do you have a ready example using RTD?

Hello @adem_marangoz,

Let me check.

Do you need MCAL or IP example?

No, I don't want MCAL. I use Freescale Semiconductor libraries.
If there are ready-made functions instead of writing directly to registers, that would be better.

What do you mean by the Freescale Semiconductor libraries?

The S32K1xx RTD has

MCAL MCU driver that manages the power modes and
low-level Power_Ip driver.

Does it mean you need an example with the Ip drivers?

low-level Power_Ip driver.

Hi @adem_marangoz,

In your other community thread, you mentioned using the legacy SDK v3.0.0:

https://community.nxp.com/t5/S32K/Wake-the-MCU-from-VLPR-using-a-GPIO-pin/m-p/2198256#M54116

This SDK includes a default example that demonstrates low-power modes, including VLPS.
