Description
S: source device
D: device for storing Gray code
Convert the binary value of the device designated by S to Gray code, and store in the device
that D designates.
The available range of S is as below. If the value exceeds the range, it’s operation error, and
the instruction is not executed.
16-bit instruction: 0–32,767
32-bit instruction: 0–2,147,483,647
Example
