A.3.3 Interrupt assignments
The functions are assigned different interrupts, depending on the operating system. APIC
mode is used.
PCI / PCIe cards and the on-board PCI / PCIe devices require PCI interrupt channels. These
interrupt channels can be shared and are plug-and-play compatible. That is, several devices
can share the same interrupt. The IRQ is assigned automatically.
The tables describe the assignment of the interrupts in the delivery state of the device.
