If TCB is connected to the Event System as an event generator, the TCB will generate a strobe on the connected event channel when the configured event condition is met.

The peripheral accepts one event input. If the Capture Event Input Enable bit (CAPTEI) in the Event Control register (TCB.EVCTRL) is written to '1', incoming events will result in an event action as defined by the Event Edge bit (EDGE) in TCB.EVCTRL. A change on event line needs to be held for at least on system clock cycle to guarantee action on event except single shot mode.
