CV is crossed in the positive counting direction (+CV crossing) or negative count-
ing direction (-CV crossing), one or multiple Outputs can be Set (S) or Reset (R).
For example Output 0 is Set on crossing CV5 in the positive counting direction and
Reset on crossing CV7 in the negative counting direction. The crossing of CV3 in
the positive counting direction results in the Setting of Output 2 and the Resetting
of Output 1.
