The valid interrupt sources are the IC, IE, IT interrupt function blocks and the CF,CH, and CI high-speed counters that are directly connected to the device inputs. Formore information, please refer to → "CF - Frequency counter", page 224, → "CH - High-speed counter", page 230 , → "CI - Incremental counter", page 237 as well.428 easyE4 11/18 MN050009 EN www.eaton.com
