For iMOTION™ IC IMC1xx, there are three types of Gatekill Input Source (Refer to section 5.2.3 or control board user manual for

detail). Please note that, if select comparator for Gatekill Input Source, the external Gatekill signal will be not used. And the signal

I_Shunt will be compared by the internal comparator with the “Gatekill Comparator Reference” value set in MCEWizard only.
