The F2837xD includes eight independent Comparator Subsystem (CMPSS) modules that are
useful for supporting applications such as peak current mode control, switched-mode power,
power factor correction, and voltage trip monitoring. The Comparator Subsystem modules have
the ability to synchronize with a PWMSYNC event.
