Analog Comparator Status Register – ACSR
Bit
Read/Write
Initial Value
• Bit 7– AC3IF: Analog Comparator 3 Interrupt Flag Bit
This bit is set by hardware when comparator 3 output event triggers off the interrupt mode defined by
AC3IS1 and AC3IS0 bits in AC3CON register.
This bit is cleared by hardware when the corresponding interrupt vector is executed in case the AC3IE in
AC3CON 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 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.
This bit is cleared by hardware when the corresponding interrupt vector is executed in case the AC1IE in
AC1CON 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 4– Reserved
• Bit 3– AC3O: Analog Comparator 3 Output Bit
AC2O bit is directly the output of the Analog comparator 2.
Set when the output of the comparator is high.
Cleared when the output comparator is low.
• Bit 2– AC2O: Analog Comparator 2 Output Bit
AC2O bit is directly the output of the Analog comparator 2.
Set when the output of the comparator is high.
Cleared when the output comparator is low.
• Bit 1– AC1O: Analog Comparator 1 Output Bit
AC1O bit is directly the output of the Analog comparator 1.
Set when the output of the comparator is high.
Cleared when the output comparator is low.
