Software trigger
A software trigger is an external signal that is controlled via a status and
control register:
on page 283: 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
Note
•
