The second approach is to use one digital input for both the start function and
the stop function. This leaves the other digital input available for the
implementation of other functions.

No effect
Inverter starts on first rising edge, stops on
second rising edge, etc
Remark: Vlow = 0 Vdc, Vhigh = 15-24 Vdc
