Comparators are used to interface analog circuits to a
digital circuit by comparing two analog voltages and
providing a digital indication of their relative magnitudes.
The comparators are very useful mixed signal building
blocks because they provide analog functionality
independent of the program execution. The Analog
Comparator module includes the following features:
• Dual comparators
• Multiple comparator configurations
• Comparator outputs are available
• Programmable output polarity
• Interrupt-on-change
• Wake-up from Sleep
• Timer1 gate (count enable)
• Output synchronization to Timer1 clock input
• Programmable voltage reference
