Note: The characteristics apply when no pin functions other than 14-bit A/D converter input are used. Absolute
accuracy does not include quantization errors. Offset error, full-scale error, DNL differential nonlinearity error,
and INL integral nonlinearity error do not include quantization errors.
Note 1. The conversion time is the sum of the sampling time and the comparison time. The number of sampling states is
indicated for the test conditions.

Note 1. The internal reference voltage cannot be selected for input channels when AVCC0 < 2.0 V.
Note 2. The 14-bit A/D internal reference voltage indicates the voltage when the internal reference voltage is input to the
14-bit A/D converter.
