Note 6-1: The quantization error (±1/2LSB) is excluded from the absolute accuracy.
Note 6-2: The conversion time refers to the period from the time when an instruction for starting a conversion process is
issued to the time the conversion results register(s) are loaded with a complete digital conversion value
corresponding to the analog input value.
