Overview
Analog Comparator Register Description
ADC Control and Status Register B – ADCSRB
The Analog Comparator compares the input values on the positive pin AIN0 and negative pin
AIN1.
When the voltage on the positive pin AIN0 is higher than the voltage on the negative pin AIN1,
the Analog Comparator output, ACO, is set. The comparator’s output can be set to trigger the
Timer/Counter1 Input Capture function. In addition, the comparator can trigger a separate inter-
rupt, exclusive to the Analog Comparator. The user can select Interrupt triggering on comparator
output rise, fall or toggle. A block diagram of the comparator and its surrounding logic is shown
in
Figure 20-1. Analog Comparator Block Diagram
Notes:
• Bit 6 – ACME: Analog Comparator Multiplexer Enable
When this bit is written logic one and the ADC is switched off (ADEN in ADCSRA is zero), the
ADC multiplexer selects the negative input to the Analog Comparator. When this bit is written
logic zero, AIN1 is applied to the negative input of the Analog Comparator. For a detailed
description of this bit, see
