AC1CON – Analog Comparator 1Control Register
Table 23-2.
Bit
Read/Write
Initial Value
• Bit 7– AC1EN: Analog Comparator 1 Enable Bit
Set this bit to enable the analog comparator 1.
Clear this bit to disable the analog comparator 1.
• Bit 6– AC1IE: Analog Comparator 1 Interrupt Enable bit
Set this bit to enable the analog comparator 1 interrupt.
Clear this bit to disable the analog comparator 1 interrupt.
• Bit 5:4– AC1IS[1:0]: Analog Comparator 1 Interrupt Select bit
These 2 bits determine the sensitivity of the interrupt trigger.
The different setting are shown in
Table 23-3.
• 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.
