Description
*U(420) multiplies the binary values in Md and Mr and outputs the result to R,
R+1.
Flags
Precautions
When *U(422) is executed, the Error Flag will turn OFF.
If as a result of the multiplication, the content of R, R+1 is 0000 hex, the
Equals Flag will turn ON.
If as a result of the multiplication, the content of the leftmost bit of R+1 is 1,
the Negative Flag will turn ON.
Examples
When CIO 000000 is ON in the following example, D00100 and D00110 will
be multiplied as 4-digit unsigned binary values and the result will be output to
D00121 and D00120.
