    NO NO NO DON'T DO IT

    Vref have to be lower than Vdd. Let's see you have a sensor who produce you a max of 1 volt. Then you select a Vref of ~1 Volt, then your ADC give you the full 10 bit conversion scale between 0-Vref. This is the use of it.

    But yeah.. check out for the minimum Vref requirement...

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
