Analog Comparator Register Description
Analog Comparator 0 Control Register – AC0CON
Figure 20-1. Analog Comparator Block Diagram
Notes:
Each analog comparator has its own control register.
A dedicated register has been designed to consign the outputs and the flags of the 3 analog
comparators.
Bit
Read/Write
Initial Value
• Bit 7– AC0EN: Analog Comparator 0 Enable Bit
Set this bit to enable the analog comparator 0.
Clear this bit to disable the analog comparator 0.
• Bit 6– AC0IE: Analog Comparator 0 Interrupt Enable bit
Set this bit to enable the analog comparator 0 interrupt.
Clear this bit to disable the analog comparator 0 interrupt.
• Bit 5, 4– AC0IS1, AC0IS0: Analog Comparator 0 Interrupt Select bit
