Hi @AsafTv
Thank you so much for your patience and hope you are well.
Appreciating that you reached our customer support in our community, I would like to help you with all the questions that you have, but I see that you opened a similar case today about a similar concern, so I will be handling both questions on the most recent thread of our community (https://community.nxp.com/t5/MCUXpresso-SDK/ADC-sequential-conversion/td-p/1404556), if it is ok for you.
Please let me know if you have more questions.
Thank you.
Sincerely,
Pablo Avalos.
