The A/D converter generates an interrupt (ADI) at the end of A/D conversion. The ADI interrupt
request can be enabled or disabled by the ADIE bit in ADCSR.
15.6
When using the A/D converter, note the following points:
15.6.1
Analog Input Voltage Range: The voltage applied to analog input pins AN
conversion should be in the range AV
AV
converter is not used, set AV
15.6.2
In board design, digital circuitry and analog circuitry should be as mutually isolated as possible,
and layout in which digital circuit signal lines and analog circuit signal lines cross or are in close
proximity should be avoided as far as possible. Failure to do so may result in incorrect operation
of the analog circuitry due to inductance, adversely affecting A/D conversion values.
Also, digital circuitry must be isolated from the analog input signals (AN

conversion is frequently performed in scan mode so that the current that charges and discharges
the capacitor in the sample-and-hold circuit of the A/D converter becomes greater than that input
