I/O
interrupt
Interrupt Input Unit 0 to 3
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.
