(for setting time-of-day interrupt)
All requirements for setting time-of-day interrupt
fulfilled? (Input for enable set and time-of-day
interrupt not active and time-of-day interrupt OB is
loaded)
If yes, set time-of-day interrupt...
...and activate time-of-day interrupt.
If input for canceling time-of-day interrupts is set,
cancel time-of-day interrupt.
