Analog Comparator 2 Control Register – AC2CON
Table 20-3.
• Bit 3– AC1ICE: Analog Comparator 1 Interrupt Capture Enable bit
Set this bit to enable the input capture of the Timer/Counter1 on the analog comparator event.
The comparator output is in this case directly connected to the input capture front-end logic,
making the comparator utilize the noise canceler and edge select features of the
Timer/Counter1 Input Capture interrupt. To make the comparator trigger the Timer/Counter1
Input Capture interrupt, the ICIE1 bit in the Timer Interrupt Mask Register (TIMSK1) must be set.
In case ICES1 bit
rising edge of AC1O is the capture/trigger event of the Timer/Counter1, in case ICES1 is set to
zero, it is the falling edge which is taken into account.
Clear this bit to disable this function. In this case, no connection between the Analog Compara-
tor and the input capture function exists.
• Bit 2, 1, 0– AC1M2, AC1M1, AC1M0: Analog Comparator 1 Multiplexer register
These 3 bits determine the input of the negative input of the analog comparator.
The different setting are shown in
Table 20-4.
