Add ADATE option per Gerben's comment

Using ADIE could give you faulty readings, as you could get an interrupt for a AD-conversion that started before you enabled the interrupts. Using ADEN will make the first conversion take longer, which you might not want. I'd set/clear the ADATE bit. Alternatively, is timing isn't that critical, you could keep the ADC running, and set sample back to zero, when you want to start recording a new set of measurements.
