There is an expression in the document like this :</P><P>"Enable and configure the ADC internal supply monitoring feature to sample and convert the fixed internal voltages of 0 V and 5 V. Then, compare the conversion results with the corresponding expected values."</P><P>" configure the ADC to convert two fixed internal constant values, followed by an application-dependent voltage value. Then, compare the conversion results with the expected values. Choose an application-dependent voltage value that is between the two fixed constant values. Perform a conversion in both directions -- from low voltage to high voltage, and from high voltage to low voltage."</P><P>I dont understand how can I read 0V and how can I control these test runtime?</P> Wed, 03 Aug 2022 09:40:45 GMT smt87 2022-08-03T09:40:45Z https://community.nxp.com/t5/S32K/ADC-Safety-Test/m-p/1482663#M16150 <P>Hi,</P><P>I want to test adc for safety mechanism.
