Section 15 A/D Converter
15.5
The A/D converter operates by successive approximation with 10-bit resolution. It has two
operating modes; single mode and scan mode. When changing the operating mode or analog input
channel, in order to prevent incorrect operation, first clear the bit ADST to 0 in ADCSR. The
ADST bit can be set at the same time as the operating mode or analog input channel is changed.
15.5.1
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 is set to 1, according to software, timer
2. When A/D conversion is completed, the result is transferred to the corresponding A/D data
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
