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.
