Error Flag will turn ON.
If as a result of the multiplication, the content of R, R+1, R+2, R+3 is 0000
hex, the Equals Flag will turn ON.
Examples When CIO 0.01 is ON in the following example, D201, D200, D211, and D210
will be multiplied as 8-digit unsigned BCD values and the result will be output
