Set scheduled interrupt
time interval.
Scheduled
interrupt
Sets up interrupt processing for I/O interrupts or scheduled interrupts. Both I/O
interrupt tasks and scheduled interrupt tasks are masked (disabled) when the
PC is first turned on. MSKS(690) can be used to unmask or mask I/O
interrupts and set the time intervals for scheduled interrupts.
(I/O Interrupts are not supported by CJ1 CPU Units.)

Clears or retains recorded interrupt inputs for I/O interrupts or sets the time to
the first scheduled interrupt for scheduled interrupts.
