4.11.14.12.5.3 Direct input function
The module features a direct input function.
This event function is 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 is generated
•
If the respective bits are different, then event number 512 is generated
