Monitoring the interrupt load
In total, no more than 8 interrupt sources are allowed to be processed in a single pro-
gram. 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. For
more information, please refer to → "CF - Frequency counter", page 224, → "CH - High-
speed counter", page 230 , → "CI - Incremental counter", page 237 as well.
