The logic analyzer will store the state given by pattern recognizer d

across the state given by a. When it sees state a, the logic

analyzer starts to store the state given by pattern recognizer e. It stores

that state until it sees the state given by

at which time it disables and

starts the process all over again. The analyzer repeats this process until

occurrences are found, the sequencer moves on to level 2. In level 2 the

state given by pattern recognizer b is stored until one occurrence of the

pattern given by pattern recognizer c is found and the logic analyzer

triggers. In level 3 nostate is stored, so the last state stored is the trigger
