●
While the ADC is on, these two phases are continuously repeated.
At the end of each conversion, the sample capacitor is kept loaded with the previous
measurement load. The advantage of this behavior is that it minimizes the current
consumption on the analog pin in case of single input channel measurement.
A/D conversion
The analog input ports must be configured as input, no pull-up, no interrupt. Refer to the “I/O
ports” chapter. Using these pins as analog inputs does not affect the ability of the port to be
read as a logic input.
In the ADCCSR register, select the CS[2:0] bits to assign the analog channel to convert.
ADC conversion mode
In the ADCCSR register, set the ADON bit to enable the A/D converter and to start the
conversion. From this time on, the ADC performs a continuous conversion of the selected
channel. When a conversion is complete:

Low power modes
The A/D converter may be disabled by resetting the ADON bit. This feature allows reduced
power consumption when no conversion is needed and between single shot conversions.
