Section 20 A/D Converter (ADC)
20.4
The A/D converter uses the successive-approximation method, and the resolution is 10 bits. It has
three operating modes: single mode, multi mode, and scan mode. Switching the operating mode or
analog input channels must be done while the ADST bit in ADCSR is 0 to prevent incorrect
operation. The ADST bit can be set at the same time as the operating mode or analog input
channels are changed.
20.4.1
Single mode should be selected when only A/D conversion on one channel is required.
In single mode, A/D conversion is performed once for the specified one analog input channel, as
follows:
1. A/D conversion for the selected channel starts 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 A/D data
3. After A/D conversion has completed, the ADF bit in ADCSR is set to 1. If the ADIE bit is set
4. The ADST bit that remains 1 during A/D conversion is automatically cleared to 0 when A/D
When the operating mode or analog input channel selection must be changed during A/D
conversion, to prevent incorrect operation, first clear the ADST bit to 0 to halt A/D conversion.
After making the necessary changes, set the ADST bit to 1 to start A/D conversion again. The
ADST bit can be set at the same time as the mode or channel selection is switched.
