Digital A/D conversion result
The conversion is monotonic, meaning that the result never decreases if the analog input does not and
never increases if the analog input does not.
If the input voltage (V

If the input voltage (V
the ADCDRMSB and ADCDRLSB registers is 00 00h.
The A/D converter is linear and the digital result of the conversion is stored in the ADCDRMSB and
ADCDRLSB registers. The accuracy of the conversion is described in the
characteristics.
