Figure 25: 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 26 shows the timing diagram for two indications within one disturbance.
