A Strobe signal is used mainly for triggering the input signals. For example, two inputs
shall be used for the parameter set selection. But the signals for the control do not
arrive exactly even, so for a short time it would be switched into an unintended set.
With active Strobe (scanning signal) the current input signals of the Strobe-dependent
inputs are accepted and kept until the next scanning.
With di.8 any input can be selected as Strobe-dependent input. With the control release
di.8 has no function since this is a static input.
With parameter di.6 the Strobe input is set. If several inputs are adjusted as Strobe
they are linked in OR-operation. At the next rising edge of the clock signal, the
Strobe signal is triggered.
