Analog Compare Negative Input
Table 4-63.
It is possible to select an internal voltage reference to replace the negative input to the Analog
Comparator. The output of a 2-bit DAC using the Internal Voltage Reference of the DAC is
available when ACIRS bit of ACSR register is set. The voltage reference division factor is
done by ACIR[1..0] of ADCSRB register.
If ACIRS is cleared, AIN0 pin is applied to the negative input to the Analog Comparator.
