Analog Comparator
Multiplexed Input
104
ATmega163(L)
It is possible to select any of the PA7..0 (ADC7..0) pins to replace the negative input to
the Analog Comparator. The ADC multiplexer is used to select this input, and conse-
quently, the ADC must be switched off to utilize this feature. If the Analog Comparator
Multiplexer Enable bit (ACME in SFIOR) is set (one) and the ADC is switched off (ADEN
in ADCSR is zero), MUX2..0 in ADMUX select the input pin to replace the negative input
to the Analog Comparator, as shown in Table 38. If ACME is cleared (zero) or ADEN is
set (one), PB3 (AIN1) is applied to the negative input to the Analog Comparator.
