Analog Comparator
The Analog Comparator compares the input values on the positive input PD6 (AIN0)
and negative input PD7 (AIN1). When the voltage on the positive input PD6 (AIN0) is
higher than the voltage on the negative input PD7 (AIN1), the Analog Comparator Out-
put, ACO, is set (one). The comparator’s output can be set to trigger the Timer/Counter1
Input Capture function. In addition, the comparator can trigger a separate interrupt,
exclusive to the Analog Comparator. The user can select interrupt triggering on compar-
ator output rise, fall or toggle. A block diagram of the comparator and its surrounding
logic is shown in Figure 43.

Analog Comparator Control
and Status Register – ACSR
Bit 7 – ACD: Analog Comparator Disable
When this bit is set (one), the power to the Analog Comparator is switched off. This bit
can be set at any time to turn off the Analog Comparator. When changing the ACD bit,
the Analog Comparator interrupt must be disabled by clearing the ACIE bit in ACSR.
Otherwise, an interrupt can occur when the bit is changed.
Bit 6 – AINBG: Analog Comparator Bandgap Select
When this bit is set, BOD is enabled and the BODEN is programmed, a fixed bandgap
voltage of 1.22V ± 0.1V replaces the normal input to the positive input (AIN0) of the
comparator. When this bit is cleared, the normal input pin, PD6, is applied to the positive
input of the comparator.
Bit 5 – ACO: Analog Comparator Output
ACO is directly connected to the comparator output.
