Figure 22: Operating sequence 5, two colors
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 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.
Timing diagram for sequence 6
Figure 23 shows the timing diagram for two indications within one disturbance.
