Is it OK if INTA, INTB and INTC pins of USB host controller are connected?

Latest Updated:08/01/2005

Question:

Is there a problem if the INTA, INTB, and INTC pins of the USB host controller are connected together?

Answer:

These pins can be connected together without problem, but since the value of the interrupt pin of the PCI configuration space that indicates the destination of interrupt requests for OHCI1, OHCI2, and EHCI is fixed, it cannot be changed.
This must be considered on the system side.
