Hi NXP

I have question about input capture by eTPU.
I can use PWM function.
So i connected the pin of PWM with the pin of input capture.
but i didn't capture any signal by input capture function.
What's wrong with my code ?
There are my code. thank you.
Any advice is helpful.

Hi,

most probably the IGF filter, which is added on some pins, is not properly set.

You can refer to below example for frequency measuring;
