15.4
The A/D converter operates by successive approximation with 10-bit resolution. It has two
operating modes; single mode and scan mode. There are two kinds of scan mode: continuous
mode and single-cycle mode. When changing the operating mode or analog input channel, in order
to prevent incorrect operation, first clear the ADST bit to 0 in ADCR. The ADST bit can be set at
the same time when the operating mode or analog input channel is changed.
15.4.1
In single mode, A/D conversion is to be performed only once on the specified single channel. The
operations are as follows.
1. A/D conversion is started when the ADST bit in ADCR is set to 1, according to software,
2. When A/D conversion is completed, the result is transferred to the A/D data register
3. On completion of conversion, the ADF bit in ADCSR is set to 1. If the ADIE bit is set to 1 at
4. The ADST bit remains set to 1 during A/D conversion. When A/D conversion ends, the ADST
15.4.2
In continuous scan mode, A/D conversion is to be performed sequentially on the specified
channels. The operations are as follows.
1. When the ADST bit in ADCR is set to 1 by software, MTU, or external trigger input, A/D
2. When A/D conversion for each channel is completed, the result is sequentially transferred to
3. When conversion of all the selected channels is completed, the ADF bit in ADCSR is set to 1.
4. Steps 2 to 3 are repeated as long as the ADST bit remains set to 1. When the ADST bit is

bit is automatically cleared to 0 and the A/D converter enters the idle state.
conversion starts on the channel with the lowest number in the group (AN0, AN1, ..., AN3).
the A/D data register corresponding to each channel.
If the ADIE bit is set to 1 at this time, an ADI interrupt is requested after A/D conversion ends.
Conversion of the first channel in the group starts again.
cleared to 0, A/D conversion stops and the A/D converter enters the idle state.
