Example 2 for setting periodical interrupt
When H4 or H5 is designated, the periodical interrupt occurs
at the specified interval regardless of interrupt processing
time.

After the periodical interrupt program completed, the next
interrupt timing is counted.
When the execution time of the periodical interrupt program is
less than 500 µs, the interrupt is carried out at every interval
specified by [S2]. However, when the execution time is 500 µs
or longer, the interval is automatically shifted in increments of
500 µs.

Regardless of the execution time of the interrupt program, it is
executed for the fixed interval.
The specified time interval for the periodical interrupt must be
longer than the time taken for the interrupt processing.
Setting for Interrupt time interval (K0 to 3000)
「S2]:
When the specified time for the periodical interrupt is longer
than the execution time of the interrupt program, the operation
cannot be carried out for the specified interval, and the CPU
may give an alarm.
