SK-AM62-LP: GPIO interrupt Pin Control

Part Number: SK-AM62-LP

I want to configure several GPIOs as interrupt pins.

On dev.ti.com, I can only find options for setting Pull UP/Pull Down resistors for GPIOs.

Do I need any other configurations?

Hello Vic Chang,

Thank you for the query.

We have Padconfig registers that could be used.

Please refer pin attributes section of the data sheet for the padconcig related information.

Please check if the below FAQ helps

Dear Kallikuppa Sreenivasa

Thank you for providing the relevant FAQ.

Let me describe the background and direction of my question:

1. A53 Linux requires external devices.
2. Two GPIO interrupts are needed.

The FAQ references interrupt settings for MCUs. I used "dev.ti.com" for A53 Pin Control configuration, where I only modified Pull UP/Pull Down resistors.
