R
is too high, this will result in a loss of accuracy due to leakage and sampling not being
completed in the alloted time.
A/D conversion
The analog input ports must be configured as input, no pull-up, no interrupt. Refer to

ADC conversion mode
In the ADCCSR register:
●
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[3:0] 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.
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.
AIN
– Select the CS[2:0] bits to assign the analog channel to convert.
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.
The EOC bit is set by hardware.
The result is in the ADCDR registers.
