Analog Comparator Register Description
Atmel ATmega16/32/64/M1/C1
Analog Comparator 0 Control Register – AC0CON
Each analog comparator has its own control register.
A dedicated register has been designed to consign the outputs and the flags of the 4 analog
comparators.
Bit
Read/Write
Initial Value
• Bit 7– AC0EN: Analog Comparator 0 Enable Bit
Set this bit to enable the analog comparator 0.
Clear this bit to disable the analog comparator 0.
• Bit 6– AC0IE: Analog Comparator 0 Interrupt Enable bit
Set this bit to enable the analog comparator 0 interrupt.
Clear this bit to disable the analog comparator 0 interrupt.
• Bit 5, 4– AC0IS1, AC0IS0: Analog Comparator 0 Interrupt Select bit
These 2 bits determine the sensitivity of the interrupt trigger.
The different setting are shown in
Table 20-1.
• Bit 3 – ACCKSEL: Analog Comparator Clock Select
Set this bit to use the 16MHz PLL output as comparator clock.
Clear this bit to use the CLK
• Bit 2, 1, 0– AC0M2, AC0M1, AC0M0: Analog Comparator 0 Multiplexer register
These 3 bits determine the input of the negative input of the analog comparator.
The different setting are shown in
