This bit is set and cleared by software. It is advised to use this bit to calibrate the ADC
when amplifier is ON. Setting this bit internally connects amplifier input to 0V. Hence,
corresponding ADC output can be used in software to eliminate amplifier-offset error.
0: Calibration off
1: Calibration on (The input voltage of the amplifier is set to 0V)
This bit is set and cleared by software. It is used together with the SPEED bit in the
ADCCSR register to configure the ADC clock speed as shown on the table below.
This bit is set and cleared by software.
