Selection of the strobe signal:
1: input x forms
strobe signal Strobe dependent:
0: not strobe dependent
1: strobe dependent
C
In general all parameters are preset, so that the input signal
(digitally filtered) directly passes through.
Strobe mode:
0: C = B at pos. slope
of strobe
1: C = B at strobe = 1
C = 0 at strobe = 0

filter
The digital filter reduces the sensitivity to disturbances at the control inputs. di.0
adjusts the reaction time of the inputs. During the reaction time a constant input state
must be at
all
inputs, before a singal is accepted as valid.
