18.4
The A/D converter operates by successive approximation with 10-bit resolution. It has two
operating modes: single mode and scan mode. When configuring the A/D converter, first set the
clock for A/D conversion. Before changing the operating mode or analog input channel, clear the
ADST bit in ADCSR to 0 to stop A/D conversion to prevent incorrect operation. The ADST bit
can be set to 1 at the same time as the operating mode or analog input channel is changed.
18.4.1
In single mode, A/D conversion is to be performed only once on the analog input of the specified
single channel.
1. A/D conversion for the selected channel is started when the ADST bit in ADCSR is set to 1 by
2. When A/D conversion is completed, the A/D conversion result is transferred to the
3. When A/D conversion is completed, the ADF bit in ADCSR is set to 1. If the ADIE bit is set

corresponding A/D data register of the channel.
to 1 at this time, an ADI interrupt request is generated.
A/D conversion ends. The A/D converter enters wait state. If the ADST bit is cleared to 0
during A/D conversion, A/D conversion stops and the A/D converter enters wait state.
