Explanation
1.
This instruction finds the sine of the value in S and stores it in D. The state of SM695 determines whether the
source value in S is in radians or degrees.
2.
If SM695 is OFF, the source value is S in radians
Radian=Degree×π/180.
3.
If SM695 is ON, the source value in S is in degrees.
Degree=Radian×180/π. (0
4.
If the conversion result is zero, SM600 is ON.
5.
The following graph shows the relation between radian and sine values.
