This function executes an interrupt task when the corresponding input signal
(up or down differentiated) is received.
The following diagrams show the input bits and terminals that are used for the
input interrupt function in each CPU Unit.
The 4 input bits CIO 0.04 to CIO 0.07 can be used for input interrupts.
