How to trigger DMA with LPIT in KW45

Hi NXP teams

I check the KW45 Reference Manual and it says "The trigger output signals from an LPIT may trigger other modules on the SoC, like the DMA, ADC, and other modules."

But the DMAMUX does not have the LPIT source.

How to trigger DMA with LPIT. Is there any example?

Best Regards

Kong

Hello Kong,

Hope you are doing well. It looks like a documentation issue.

Let me check internally. I will let you know as soon as I have a response.
