Chapter 6 Applied Instructions 6.2.2 Explanation of Arithmetic Instructions Symbol S 1 ： Augend S 2 ： Addend D ： Sum 6_ Explanation 1. This instruction adds the binary value in S 2 to the binary value in S 1 , and stores the sum in D . 2. Only the 32-bit instructions can use the 32-bit counter, but not the device E. 3. Instruction flags: SM600 (zero flag), SM601 (borrow flag), and SM602 (carry flag) 4. When the operation result is zero, SM600 is ON. Otherwise, it is OFF. 5. For 16-bit binary values, when the operation result exceeds the range of 16-bit binary values, SM602 is ON. Otherwise, it is OFF.
