Explanations:
1. If the instruction is not a pulse execution one, the content in the designated device D will plus “1”
in every scan period whenever the instruction is executed.
2. In 16-bit operation, 32,767 pluses 1 and obtains -32,768. In 32-bit operation, 2,147,483,647
pluses 1 and obtains -2,147,483,648.
3. The operation results will not affect any flags.
