Analog Comparator
Multiplexed Input
2502K–AVR–10/06
It is possible to select any of the ADC7..0 pins to replace the negative input to the Ana-
log Comparator. The ADC multiplexer is used to select this input, and consequently, the
ADC must be switched off to utilize this feature. If the Analog Comparator Multiplexer
Enable bit (ACME in SFIOR) is set and the ADC is switched off (ADEN in ADCSRA is
zero), MUX2..0 in ADMUX select the input pin to replace the negative input to the Ana-
log Comparator, as shown in Table 81. If ACME is cleared or ADEN is set, AIN1 is
applied to the negative input to the Analog Comparator.
