Register Description
ADC Control and Status Register B – ADCSRB
ADC Multiplexer
The Analog Comparator compares the input values on the positive pin (AIN1) and negative pin
(AIN0). When the voltage on the positive pin is higher than the voltage on the negative pin, the
Analog Comparator output, ACO, is set. The comparator can trigger a separate interrupt,
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 18-1. 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 positive input to the Analog Comparator. When this bit is written
logic zero, AIN1 is applied to the positive input of the Analog Comparator.
When the Analog to Digital Converter (ADC) is configured as single ended input channel, it is
possible to select any of the ADC[10..0] pins to replace the positive input to the Analog Com-
parator. The ADC multiplexer (MUX[4..0]) is used to select this input, and consequently, the
ADC must be switched off to utilize this feature.
