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.
