Added new SR652, SR653 for displaying number of pulse in ramp-up area and new SR654, SR655 for
displaying number of pulse in ramp-down area.
10. If the output has entered the ramp-down process when the external input interrupt trigger occurs, the instruction
completes the output of the number of pulses specified by S
