The n which is 2 in the 16-bit instruction has the same meaning as the n which is 1 in the 32-bit

instruction.

16 - bit instruction: n= 6

Additional remark:

1. If the values in m

executed, SM0 is ON, and the error code in SR0 is 16#2003.

2. If S~S+n-1 exceed the device range, the instruction is not executed, SM0 is ON, and the error

code in SR0 is 16#2003.

3. If the value in n exceeds the range, the operation error occurs, the instruction is not executed,

SM0 is ON, and the error code in SR0 is 16#200B.

4. Due to the fact that the use of the instruction TO decreases the execution efficiency of the CPU

module and that of the I/O module, users should use it less often.

5. The descriptions of the error codes:
