Page 45: Interrupt Multiplexing
72XX Series User’s Manual 4.3 Interrupt Multiplexing 4.3.1 Architecture The 7248/96 series products have a powerful and flexible interrupt multiplexing circuit which is suitable for many applications. The board is capable of accepting Dual Interrupts. The dual interrupt means that the hardware can generate two interrupt request sig- nals at the same time and the software can service these two request signals by ISR. -
Page 46: Note For Dual Interrupts
72XX Series User’s Manual 4.3.3 Note for Dual Interrupts The PCI controller of PCI-7224/7248/96 can receive two hardware IRQ sources. However, a PCI controller can generate only one IRQ to PCI bus, the two IRQ sources must be distinguished by ISR of the application software if the two IRQ are all used. -
