5.2 Comparator (COMP)

For STM8, STML Value line has comparators, but S series and the rest of L series do not. As for MSPM0, L series offers integrated comparators as optional peripherals and C series devices do not. In both families of devices comparators are denoted as COMPx, where the 'x' final character refers to the specific comparator module being considered. The comparator modules can take inputs from various internal and external sources, and can be used to trigger changes in power mode or truncate/control PWM signals. A summary of how the MSPM0 and STM8 comparator modules compare feature-by-feature is included in Table 5-3.

(1) The 8-bit DAC is integrated in COMP.
(2) When enable exchange inputs mode, the input signals of comparator positive and negative terminals are exchanged. Additionally, the output signal from the comparator is inverted too.
