COMP peripherals
The STM8L products feature two zero-crossing comparators COMP1 and COMP2 that
share the same current bias. For the STM8L10x sub-family, the COMP1 and COMP2 share
also the reference voltage.
Each comparator has two inputs: inverting and non inverting inputs. The
STM8L15x/STM8L16x sub-family offers more capabilities than the STM8L10x sub-family in
terms of number and configuration of these inputs.
The following table shows the availability of the COMPx inverting and non inverting inputs in
both sub-families.
