   No, unless you mean VAVCC            01/01/70 00:00      
      VAVCC usable as ADC reference voltage?            01/01/70 00:00

            'can" "should' and 'good' are 3 different words            01/01/70 00:00      
   varef is specified 2,4...3V range            01/01/70 00:00      
      but not if you want any precision            01/01/70 00:00      
         why not            01/01/70 00:00
