The following relationship exists between the analog input voltage input to the analog input pins (ANI0 to
ANI11 or ANI0 to ANI15) and the A/D conversion results (A/D conversion result register (ADCR)).
The following shows the relationship between the analog input voltage and A/D conversion results.
