Wakeup A core Using GPIO in IMX8ULP

Hello,

I'm using the i.MX8ULP and have connected two push buttons to PTE11 and PTE14. Now A core is in sleep mode and M core is Running, and I want to wake up the A core when a button is pressed.

However, after checking the reference manual, I found that PTE11 and PTE14 are not linked to WUU1. So, is it possible to wake up the A core using these pins? If yes, how can I do that?

If not, can I at least get an interrupt on the M core when these buttons are pressed? Is there any way to use these pins on the M core?

Thanks!
