Operation
ON if the specified range for P, M, or F is exceeded.
ON if PLS2(887) or ORG(889) is already being executed
to control pulse output for the specified port.
ON if SPED(885) or INI(880) is used to change the mode
between continuous and independent output during pulse
output.
ON if SPED(885) is executed in an interrupt task when an
instruction controlling pulse output is being executed in a
cyclic task.
ON if SPEC(885) is executed in independent mode with
an absolute number of pulses and the origin has not been
established.
