Events which can trigger a hardware interrupt

Which events can trigger a hardware interrupt?
A hardware interrupt is triggered if the condition for changing the respective status bit or
event bit in the feedback interface is fulfilled.
The EventType tag, among others, is entered in the start information of the assigned
hardware interrupt OB when a hardware interrupt is triggered. The EventType tag specifies
the number of the event type to which the event triggering the interrupt belongs.
You can configure hardware interrupts to be triggered for the following event types:
Hardware interrupt
Internal gate opening (Gate start)
Internal gate closing (Gate stop)
Overflow (high counting limit violated)
Underflow (low counting limit violated)
Comparison event for DQ0 occurred
Comparison event for DQ1 occurred
Zero crossing
New Capture value available
Synchronization of the counter by an external signal
Change of direction
Not for SSI absolute encoder
1)
Can only be configured in Counting mode
2)
The feedback bit STS_DIR has the default value "0". A hardware interrupt is not triggered when
3)
the first counter value or position value is changed immediately after switching on the technology
module in
You can activate any combination of events to trigger hardware interrupts.
