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
N
interrupts and set the time intervals for scheduled interrupts.
S
(I/O Interrupts are supported by CS-series PCs only.)
Reads the current interrupt processing settings that were set with MSKS(690).
N
D
Clears or retains recorded interrupt inputs for I/O interrupts or sets the time to
the first scheduled interrupt for scheduled interrupts.
