Example

When R010 is ON, the data of D0050 is multiplied by the data of RW05, and the result is stored in double-length register D0101×D0100 (upper 16-bit in D0101 and lower 16-bit in D0100).

If the data of D0050 is 52500 and the data of RW05 is 30, the result 1575000 is stored in D0101×D0100.

D0050	52500
RW05	´	D0101×D0100
	30

Note

·This instruction handles the register data as unsigned integer.
