Outline of operation
● This instruction has no effect on the operation results to that point. The program will operate
in the same manner whether or not the NOP instruction is used.
● The NOP instruction may be used to make it easy to view the program code when reviewing
and/or modifying it.
● To erase an instruction without changing the program address, write the NOP instruction
over it.
● To send the address of a program portion without modifying the program, insert the NOP
instruction.
● For example, this is a convenient means of breaking a long program into several blocks.
