 The contents of the two source devices are multiplied together and the result is stored at the
destination device in the format of32 bits. As the above chart: when (D0)=8, (D2)=9, (D5, D4)
=72.
 The result’s highest bit is the symbol bit: positive (0), negative (1).
 In the above example, when X0 is ON, the instruction will be executed in every scanning
period.
