10.4.2 Input voltage and conversion results
A/D conversion result (stored in the 10-bit A/D conversion result register (ADCR)) is shown by the following
expression.
The relationship between the analog input voltage input to the analog input pins (ANI0 to ANI7) and the theoretical
or
where, INT( ):
Figure 10-13 shows the relationship between the analog input voltage and the A/D conversion result.
