Software trigger
A software trigger is an external signal that is controlled via a status and control
register:
62Ch on page 206: to activate software trigger set bit [0] to 1.
The behavior is different dependent on the trigger mode used:
•
Edge mode, programmable mode: trigger is automatically reset (self-
cleared).
•
Level mode: trigger is active until software trigger register is reset
manually.

Debounce
Only for input ports:
There is an adjustable debounce time for trigger: separate for each input pin.
The debounce time is a waiting period where no new trigger is allowed. This
helps you to set exactly one trigger.
To set this feature in an advanced register: see
To set this feature in SmartView: Trig/IO tab, Input pins table, Debounce
column.
Note
•
Switching trigger delay to ON also switches external
Trigger_Mode_0 to ON.
•
This feature works with external Trigger_Mode_0 only.
