Limitations
R and R+1 must be in the same data area.
Description
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.

Example
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.
