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.
Interrupt Input Unit 0 to 3
I/O

Mask (1) or unmask (0)
interrupt inputs 0 to 7.
