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.

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.
