I couldn't understand if the first conversion after ADC is enabled (ADEN 
bit) must be discarded or not.

The datasheet suggests to discard the first conversion result after 
changing the reference signal, but nothing after enabling ADC or 
changing input signal (ADMUX).

The only note is about the conversion time that is longer for the first 
conversion after ADC is enabled.

I'm asking this question because I'm noting a different behaviour if I 
start conversion and enable ADC at the same time for each conversion 
against leaving ADC enabled and starting only the conversion (ADSC bit).
