I'm testing a 9S08QG8 micro.
When I test the ADC it work like a 12bits converter.
I"m working with 3,3V and when I read VrefH on the ADCRH: ADCRL the FFE value.
I believe that if the ADC is 10bits I would have to read 3FF.
With a trimpot conected to 3,3V  and changing from 0V to 3,3V the register change from 0000 to 0FFE 
Which is my error??
or the ADC is it 12 Bits ??
Best Regards
Eugenio
