Example
The FSUM instruction adds up the values of the 3 single precision floating points in (D1, D0), (D3, D2), (D5, D4) and
stores the result in (D11, D10).
[( D1, D 0)+( D3, D 2)+(D5 , D4)]
(D1, D0)
(D3, D2)

(D5, D4)
Additional remarks
1.
If the value in n is not between 1–256, the instruction is not executed, SM0 is ON, and the error code in SR0 is
16#200B.
2.
If S+2*n-1exceeds the device range, the instruction is not executed, SM0 is ON, and the error code in SR0 is
16#2003.
3.
If the value in S exceeds the range of the floating point numbers that can be shown, the instruction is not executed,
SM0 is ON, and the error code in SR0 is 16#2013.
