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 lines. These interrupt
lines can be shared and are plug-and-play compatible. In other words, several devices can
share one interrupt. The IRQ is assigned automatically.
The table describes the assignment of the interrupts in the delivery state of the device.
