Analog Comparator (ACMP) Block Description
14.1
The ACMP has the following features:
14.2
The block diagram for the analog comparator module is shown below.
14.3
The ACMP has two analog input pins: ACMP1– and ACMP1+. Each of these pins can accept an input
voltage that varies across the full operating voltage range of the MCU. When the ACMP1+ is configured
to use the internal bandgap reference, ACMP1+ is available to be as general-purpose I/O. As shown in the
block diagram, the ACMP1+ pin is connected to the comparator non-inverting input if ACBGS is equal to
logic 0, and the ACMP1– pin is connected to the inverting input of the comparator.
