Functions The edge to be used can be chosen between rising and falling.
Rising: Triggered when a pulse rises from the low level
(between 0 V and 0.8 V) to the high level (between 2.5 V
and 10 V).
Falling: Triggered when a pulse falls from the high level
(between 2.5 V and 10 V) to the low level (between 0 V
and 0.8 V), or when the terminals are connected with
each other.
