7647G–AVR–09/11
Analog Comparator 3 Control Register – AC3CON
Bit 3 – Res: Reserved Bit
This bit is an unused bit in the ATmega16/32/64/M1/C1, and will always read as zero.
• Bit 2, 1, 0– AC2M2, AC2M1, AC2M0: Analog Comparator 2 Multiplexer register
These 3 bits determine the input of the negative input of the analog comparator.
The different setting are shown in
Table 20-6.

Initial Value
• Bit 7– AC3EN: Analog Comparator 3 Enable Bit
Set this bit to enable the analog comparator 3.
Clear this bit to disable the analog comparator 3.
• Bit 6– AC3IE: Analog Comparator 3 Interrupt Enable bit
Set this bit to enable the analog comparator 3 interrupt.
Clear this bit to disable the analog comparator 3 interrupt.
• Bit 5, 4– AC3IS1, AC3IS0: Analog Comparator 3 Interrupt Select bit
