AKD Benutzerhandbuch | 25.7.3 CAP0.EVENT, CAP1.EVENT
The event mode controls use of the precondition logic. If this field is not 0, then the precondition input
is selected by CAPx.TRIGGER. If this field is 1, then the precondition edge is selected by the
CAPx.PREEDGE. The four event modes are listed below.
Event
0 Precondition settings ignored.
1 Trigger on first trigger event after selected edge on precondition
input.
2 Trigger on first trigger event to occur while precondition input is 1
3 Trigger on first trigger event to occur while precondition input is 0.
Example
Event 0
The following diagram shows an example of Event = 0 (trigger on edge, trigger edge = rising). In this
mode, the precondition logic is ignored.
Figure 1: Trigger Edge Mode
Events 2 and 3 (Trigger edge while precondition = 0 or 1)
In these events, the precondition logic samples the current (post-filter) state of the selected pre-
condition source input. The capture engine looks for a trigger edge while the precondition input is at a
"1" or "0" state.
