When the execution condition is OFF, MUL(32) is not executed. When the
execution condition is ON, MUL(32) multiplies Md by the content of Mr, and
places the result In R and R+1.

When IR 00000 is ON with the following program, the contents of IR 013 and
DM 0005 are multiplied and the result is placed in HR 07 and HR 08. Example
data and calculations are shown below the program.
