Sequence 6 LatchedReset-S
In this mode all activated LEDs, which are set to Sequence 6 (LatchedReset-S), are automatically
reset at a new disturbance when activating any input signal for other LEDs set to Sequence 6
LatchedReset-S. Also in this case indications that are still activated will not be affected by manual

reading and storing of active signals is performed. LEDs set for sequence 6 are completely
independent in its operation of LEDs set for other sequences.
