Chapter 6 Applied Instructions 5. 32-bit binary division: Quotient S 1 S 2 S 1 S 2 +1 D+1 D +1 b15.....b0 b15.....b0 b15.....b0 b15.....b0 b15.....b0 b15.....b0 / = D occupies two consecutive devices. The quotient is stored in ( D +1, D ). Example When X0.0 is ON, the instruction divides the dividend in D0 by the divisor in D10, and stores the quotient D20. Whether the quotient is a positive value or a negative value depends on the leftmost bit in D20. Additional remarks 6_ 1. If the device is not available, the instruction is not executed, SM0 will be ON, and the error code stored in SR0 is 16#2003. 2.
If the divisor is 0, the instruction is not executed, SM0 will be ON, and the error code stored in SR0 is 16#2012. 3. If you want to store the remainder, use the “/” instruction (Dividing binary values). Refer to the explanation for the “/” instruction (API 0103) for more information. 6-77
