Hi darcy XU ,

    Thank you for your interest in the NXP kinetis product, I would like to provide serivce for you.

   Seems after the get channelconversion value, the status is cleared.

    I printf the AFE_SR register, after trigger channel, and wait until conversion complete, you can find the COC00 and the RDY0 is 1.

I am testing SDK_2.2.0_MKM34Z256xxx7\boards\twrkm34z75m\driver_examples\afe\polling

 Do you also test the same project? What's the IDE you are using?

Kerry
