Interrupt Controllers
Using interrupts, hardware can request software services. If non-Plug and Play software is being
used, the interrupt may need to be moved for software application or driver compatibility. Some
interrupts cannot be moved. Fifteen interrupts can be used with a cascade connection of
8259INTC x 2. The table shows default interrupt level assignments 0 through 15, in order of
decreasing priority.
