Only pins 4 through 7 can be configured as "coupled" pins. The designated pins will function as both
an input and an output, with a negative transition on one pin providing the sequence signal to the
other pins. The polarity of the pins is not programmable; it is set to NEGative.
In this example, pin 6 is configured as the output On control. Pin 7 is configured as the output Off
control. The ground or Common pins are connected together.
