SET INTER-
RUPT MASK MSKS @ Sets up interrupt processing for I/O interrupts or scheduled inter-
rupts. 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 inter-
vals for scheduled interrupts.
CLEAR

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