9.0
The comparator can be used to interface analog
circuits to a digital circuit by comparing two analog
voltages and providing a digital indication of their
relative magnitudes. The comparator is a very useful
mixed signal building block because it provides analog
functionality independent of the program execution.
The Analog Comparator module includes the following
features:
• Programmable input section
• Comparator output is available internally/externally
• Programmable output polarity
• Interrupt-on-change
• Wake-up from Sleep
• PWM shutdown
• Timer1 gate (count enable)
• Output synchronization to Timer1 clock input
• Programmable voltage reference
• User-enable Comparator Hysteresis
