12.5 Interrupts
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.
12.6 Usage Notes
When using the A/D converter, note the following points:
Analog Input Voltage Range: During A/D conversion, the voltages input to the analog input pins
