Description:
As long as input 1 is TRUE and input 2 is FALSE, the set pulse pattern is output. The pulse pat-
tern at the output always starts with TRUE. The clock pattern is defined by the on-time and the
off-time. The time set in P1 is the on-time (High) and the time set in P2 is the off-time (Low).
Via the output buffer, the output signal is globally available.
Inputs Superior Set and Superior Reset are connected in series with the function. Levels at Set
input I1 and Reset input I2 are processed internally. As soon as the Superior Set or Superior
Reset is reset, the output is switched to the internally saved value.
