DNL_ADC: DNL is defined as the difference between the ideal and the measured code transitions for successive A/D code outputs
expressed in LSBs. The measured transfer curve is adjusted for Offset and Fullscale errors before calculating DNL.
INL_ADC: The deviation of the measured transfer function of an A/D converter from the ideal transfer function. The INL error is also
defined as the sum of the DNL errors starting from code 00h to the code where the INL measurement is desired. The measured trans-
fer curve is adjusted for Offset and Fullscale errors before calculating INL.
