Chapter 8 Analog Comparator (S08ACMPV2)
8.4
Functional Description
The analog comparator can be used to compare two analog input voltages applied to ACMP+ and ACMP-;
or it can be used to compare an analog input voltage applied to ACMP- with an internal bandgap reference
voltage. ACBGS is used to select between the bandgap reference voltage or the ACMP+ pin as the input
to the non-inverting input of the analog comparator. The comparator output is high when the non-inverting
input is greater than the inverting input, and is low when the non-inverting input is less than the inverting
input. ACMOD is used to select the condition which will cause ACF to be set. ACF can be set on a rising
edge of the comparator output, a falling edge of the comparator output, or either a rising or a falling edge
(toggle). The comparator output can be read directly through ACO. The comparator output can be driven
onto the ACMPO pin using ACOPE.
