CHAPTER 28 COMPARATOR
28.1 Overview
28.1 Overview
The comparator monitors the two analog input voltages, and automatically
generates an interrupt upon detection of a change in the edge of comparator
output.
■ Function of Comparator
The function of the comparator is to monitor the two analog input voltages and compare them.
Using the voltage of the non-inverting analog input (positive input) as a reference voltage, the
comparator outputs "H" if the voltage of the inverting analog input voltage (negative input) is
lower than the reference voltage; otherwise, it outputs "L". In addition, upon detection of a
rising edge or falling edge of the comparator output, the comparator outputs a corresponding
interrupt.
