4.11.17.12.5.3 Direct input functions
The module has 2 "direct input functions"
These event functions are based on comparator functionality. If the event configured in the
"CfO_DIREKTIOevent0IDwr" register occurs, the event function compares the status of all Direct I/O channels
enabled in the "CfO_EvCompMask" register to a status defined in the "CfO_DIREKTIOeventcompState" register.
The event that is generated depends on the results of this comparison.
•
If the respective bits are the same, then event number 513 or 545 is generated
•
If the respective bits are different, then event number 512 or 544 is generated
