On the other hand, the device manufacturer does not decree what the arch and supporting chipset will *accept*. There's no guarantee that all trigger types will be supported. For instance on my ASB2305 board, I've got an on-chip PIC that will accept any of the four trigger types, but the PCI bus interrupt line attached to one of the external interrupt pins will *only* accept low-level triggered. In such a case, the bus *must* override anything set by one of the devices. David
