+\subsection{Data Format}
+The module has two distinct output formats that can be selected before synthesis and cannot be changed during runtime.
+Both share a common first word, containing the received running number as well as status- and the error-bits.
+If indicated in the header, two additional words storing information to reconstruct the arrival time of this MBS data follow:
+
+In this case, the first additional word (2nd in stream) holds a timestamp with a granularity of 5~ns.
+The timestamp was reset by the arrival of the timing trigger belonging to the LVL1 trigger as indicated by the 3rd word in the data stream.
+Observe that this information is only valid, if a timing trigger was received not more than 20~s before the arrival of the data word.
