Note 6-1 : The quantization error (±1/2LSB) is excluded from the absolute accuracy value.
Note 6-2 : The conversion time refers to the interval from the time the instruction for starting the converter is issued till
the time the complete digital value corresponding to the analog input value is loaded in the required register.
