10.5 Input Voltage and Conversion Results
The relationship between the analog input voltage input to the analog input (ANI0 to ANI10, internal reference voltage)
and the theoretical A/D conversion result (stored in the 10-bit A/D conversion result register (ADCR)) is shown by the
following expression.
SAR = INT
