2.2.3 Edge Detector

The edge detector can be enabled to generate a pulse when a rising edge on the input is detected. To detect a falling edge, the truth table may be programmed to provide the opposite level. An example is to send a pulse with the Event System to trigger another peripheral, e.g. a timer, every time the truth table has output HIGH(1).
