41.6.2.4.6 Direction Event Action

The direction event action can be selected in the Event Control register (EVCTRL.EVACT1 = 0x2, DIR). When this event is used, the asynchronous event path specified in the event system must be configured or selected. The direction event action can be used to control the direction of the counter operation depending on external events level. When received, the event level overrides the Direction settings (CTRLBSET.DIR or CTRLBCLR.DIR) and the direction bit value is updated accordingly.
