1. How can I remove the calibration performed on an ADC module?.

I have calibrated ADC0 module for reading the voltage in a particular channel. After reading the value I want to remove the calibration applied to that channel.

Hello rijil.kp@tataelxsi.co.in‌,

The calibration registers CLPS, CLP3, CLP2, CLP1, CLP0, CLPX, CLP9 and the offset ones can be written after the calibration process at any time but this is not recommendable, as the reference manual says:

After the ADC has been configured and calibrated, no further calibration is required as long as the power is maintained.

The calibration is not channel dependant, to know better practices for the ADC module I will suggest checking the following application note.

Let me know if this helps you.

Best Regards,

Alexis Andalon
