3.4.3.1
Mode
The External Input is edge-triggered and can be set to trigger to rising-edge trigger (Low or
Closed to High or Open), falling-edge triggered (High or Open to Closed or Low) or both. An
attempt to set the Mode to 0x00 (i.e. to disable both rising and falling edges) is ignored by the
Sensor.
Application Examples:
•
Door Open/Close detection would use both rising and falling triggers to detect when the
door was opened and when it was closed.
