Analog Comparator 2 Control Register – AC2CON
Bit
Read/Write
Initial Value
• Bit 7– AC2EN: Analog Comparator 2 Enable Bit
Set this bit to enable the analog comparator 2.
Clear this bit to disable the analog comparator 2.
• 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 17-3.
• Bit 3– Reserved
• 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 17-4.
