Analog Comparator 1Control Register – AC1CON
Bit
Read/Write
Initial Value
• Bit 7– AC1EN: Analog Comparator 1 Enable Bit
Set this bit to enable the analog comparator 1.
Clear this bit to disable the analog comparator 1.
• Bit 6– AC1IE: Analog Comparator 1 Interrupt Enable bit
Set this bit to enable the analog comparator 1 interrupt.
Clear this bit to disable the analog comparator 1 interrupt.
• Bit 5, 4– AC1IS1, AC1IS0: Analog Comparator 1 Interrupt Select bit
These 2 bits determine the sensitivity of the interrupt trigger.
The different setting are shown in
Table 16-1.
• Bit 3– Reserved
• Bit 2, 1, 0– AC1M2, AC1M1, AC1M0: Analog Comparator 1 Multiplexer register
These 3 bits determine the input of the negative input of the analog comparator.
The different setting are shown in
Table 16-2.
