IRQ[0:3] Interrupt Requests
IRQ
[0:3] provides interrupt requests to Interrupt Controllers for external devices such as:
• graphics controllers
• PCI interrupt controller
•ATAs
• transport de-multiplexers
• external I/O devices, etc.
These interrupts are programmable as edge or level sensitive. See Figure 7-1.
