4.13 System Interrupts

CPCI-6200 provides several sources of interrupts that are handled by the processor. The
processor supports 12 external interrupts. Interrupts coming through PCI Express switch
(PEX8624) are routed to the first four interrupts (IRQ0 – IRQ3). Interrupts coming through the
PCI Express expansion interface are routed to the next four interrupts (IRQ4-IRQ7). The
remaining processor interrupts (IRQ8-IRQ11) are connected to LBPC CPLD interrupt sources.
