Software trigger
A software trigger is an external signal that is controlled via a status and
control register: 62Ch on page 228: 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 exact one trigger.
To set this feature in an advanced register: see Chapter Debounce time on
page 152.
Note

• Switching trigger delay to ON also switches external
Trigger_Mode_0 to ON.
• This feature works with external Trigger_Mode_0 only.
