Detailed Description
ATLAS Level-1 Event Counter.This entity counts ATLAS Level-1 Events (needed for TDAQ ID) by taking the Level-1-Accepts from the LTP as reference. Gets reset by dedicated Event Counter Resets, which are also counted, for ID purposes during a run. Also provides the possibility of loading the values of both ECR & L1A Counters.
