The total conversion time:
t
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 behaviour 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:
●
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:
●
●
A read to the ADCDRH or a write to any bit of the ADCCSR register resets the EOC bit.
To read the 10 bits, perform the following steps:
1.
2.
3.
To read only 8 bits, perform the following steps:
1.
2.
Changing the conversion channel
The application can change channels during conversion.
When software modifies the CH[2:0] bits in the ADCCSR register, the current conversion is
stopped, the EOC bit is cleared, and the A/D converter starts converting the newly selected
channel.
CONV =
cycles) and the C
the optimum analog to digital conversion accuracy.
Select the CS[2:0] bits to assign the analog channel to convert.
The EOC bit is set by hardware.
The result is in the ADCDR registers.
