Chapter 9 Analog Comparator (S08ACMPV3)
9.1.4
The block diagram for the analog comparator module is shown
9.2
The ACMP has two analog input pins, ACMPx+ and ACMPx− and one digital output pin ACMPxO. Each
of these pins can accept an input voltage that varies across the full operating voltage range of the MCU.
As shown in
ACMPx+ pin is connected to the comparator non-inverting input if ACBGS is a 0. As shown in
the ACMPxO pin can be enabled to drive an external pin.
The signal properties of ACMP are shown in
