System Interrupts

The processor has two controllers, supplying 16 IRQs.
Below are assignments in decreasing priority.

Note: IRQ9, IRQ10, IRQ11, IRQ12, IRQ15, IRQ3, IRQ4,
IRQ5 and IRQ7 can be redirected to PCI add-in boards.

The PCI standard has a 4-IRQ limitation. Some PCI add-in
boards do not require IRQs. Some can share an IRQ with
another board of the same model and manufacture. Check the
add-in board’s documentation for IRQ information.
