7710E–AVR–08/10
Analog Comparator Status Register – ACSR
• Bit 6– AC2IE: Analog Comparator 2 Interrupt Enable bit
Set this bit to enable the analog comparator 2 interrupt.
Clear this bit to disable the analog comparator 2 interrupt.
• Bit 5, 4– AC2IS1, AC2IS0: Analog Comparator 2 Interrupt Select bit
These 2 bits determine the sensitivity of the interrupt trigger.
The different setting are shown in
Table 20-5.
• 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.
Bit
Read/Write
Initial Value
• Bit 6– AC2IF: Analog Comparator 2 Interrupt Flag Bit
This bit is set by hardware when comparator 2 output event triggers off the interrupt mode
defined by AC2IS1 and AC2IS0 bits in AC2CON register.
This bit is cleared by hardware when the corresponding interrupt vector is executed in case the
AC2IE in AC2CON register is set. Anyway, this bit is cleared by writing a logical one on it.
This bit can also be used to synchronize ADC or DAC conversions.
• Bit 5– AC1IF: Analog Comparator 1 Interrupt Flag Bit
This bit is set by hardware when comparator 1 output event triggers off the interrupt mode
defined by AC1IS1 and AC1IS0 bits in AC1CON register.
