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
reset, that is, immediately after the positive edge of that the manual reset has been executed a
new 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.
