41.6.2.4.8 Decrement Event Action

The decrement event action can be selected in the Event Control register (EVCTRL.EVACT1 = 0x4, DEC) and can change the Counter state when an event is received. When the TCE1 (TCCx_EV1) event is received, the counter decrements regardless of the direction setting (CTRLBSET.DIR or CTRLBCLR.DIR).
