Trigger Mode: Four trigger modes are available:
Level: the trigger is asserted while the input is active.
Rising edge: the trigger is asserted only at the rising edge of the input.
Falling edge: the trigger is asserted only at the falling edge of the input.
Rising/Falling edge: the trigger is asserted both at the rising and at the falling edge of the input.
Start/end offset: the interval during which the trigger is asserted can be extended in both directions
with start and end offsets.
