POINT
(1) Set the memory write protect range according to the address (step
number) of each memory area (sequence program, comment, sampling
trace, status latch, file register).
(2) Do not use the memory write protect function when executing a sampling
trace or status latch since it will make it impossible to store the data in the
memory.
