Analog Comparator 3 Control Register – AC3CON
Bit
Read/Write
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
These 2 bits determine the sensitivity of the interrupt trigger.
The different setting are shown in
Table 16-5.
• Bit 3– AC3OEA: Analog Comparator 3 Alternate Output Enable
Set this bit to enable the analog comparator 3 alternate output pin.
Clear this bit to disable the analog comparator 3 alternate output pin.
• Bit 2, 1, 0– AC3M2, AC3M1, AC3M0: Analog Comparator 3 Multiplexer register
These 3 bits determine the input of the negative input of the analog comparator.
The different setting are shown in
Table 16-6.
