Explanation
1. This instruction adds up the single precision floating points in the n devices starting from the device specified by S,
divides the sum by the value in n, then stores the mean of the sum in D.
2. For 16-bit instructions, the value in n must be between 1–256,
3. Instruction flags: SM600 (zero flag), SM601 (borrow flag), SM602 (carry flag):

When the operation result is zero, SM600 is ON. Otherwise, it is OFF.

If the value while adding or the absolute result of the operation is less than the floating point number that can
be shown, the D=16#FF800000 and the borrow flag SM601 is ON.

If the value while adding or the absolute result of the operation is larger than the floating point number that can
be shown, the D=16#7F800000 and the carry flag SM602 is ON.
Example
When X0.0 is ON, the instruction adds the values of the 3 single precision floating points in (D1, D0), (D3, D2), (D5, D4)
and then divides the addition result by 3, then stores the result in (D11, D10).
