AH500 Programming Manual Symbol: S ： Data source Word/Double word n ： Data length Word/Double word D ： Operation result Double word/Long word Explanation: 1. The signed decimal values in S ~ S + n -1 are added up, and the sum is stored in the register specified by D . S +1 S +2 S Binary values +3 S +5 S +4 S S +1 S Binary values 2. The operand n used in the 16-bit instruction should be within the range between 1 and 256, and the operand n used in the 32-bit instruction should be within the range between 1 and 128. 3. Only the 32-bit instructions can use the 32-bit counter. Example: When the instruction WSUM is executed, the values in D0~D2 are added up, and the sum is stored in D10.
