An event is added to the TCU where it WAITS for 1 crossing. It then sets the trigActionWord and is forwarded to the trigInterface . The trigActionWord is determined from the L0 Word which contains information concerning the type of event which occurred and busy information from the dectectors. It is here that deadtime is recorded.
