Explanation
1. This instruction takes the device specified by S as a pointer. This instruction writes the data in the device specified
by the value of the pointer into the device specified by D and clears it to 0, and decrements the value in the device
specified by S by one. When the value in the device specified by S is equal to 0, the instruction stops reading the
data, and sets the zero flag SM600 is ON.
