The program shown below is an example of a program that meets the above condition. Do not creates
such a program.

Because the BTM0CY flag read instruction at
# in this program is executed at every 500 instructions, once
the BTM0CY flag happens to be set at the timing of the instruction at
#, a CE reset will not occur forever.
In addition, because the instruction execution time is 12

s (1/83.33 kHz) during the operation of the IDC,
do not create a cyclic program that meets the following condition.
