Interrupt Control Instructions
Section 3-20
3-20-1 SET INTERRUPT MASK: MSKS(690)
Purpose
Controls whether I/O interrupt tasks and scheduled interrupt tasks are exe-
cuted. When the program execution starts, the interrupt inputs that generate I/
O interrupt tasks are masked (disabled), and the internal timers creating the
timer interrupts that generate scheduled interrupt tasks are stopped.
Use MSKS(690) to enable the I/O interrupts and timer interrupts, so that the
corresponding interrupt tasks can be executed.
