ADC Safety Test

Hi,

I want to test adc for safety mechanism. There is an expression in the document like this :

"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."

" 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."

I dont understand how can I read 0V and how can I control these test runtime?
