Interrupt Line (INT_LN) — RO. This data is not used by the Intel
communicate to software the interrupt line that the interrupt pin is connected to.
Interrupt Line (INT_LN) — RO. This value tells the software which interrupt pin each
USB host controller uses. The upper 4 bits are hardwired to 0000b; the lower 4 bits are
determine by the Interrupt Pin default values that are programmed in the memory-
mapped configuration space as follows:
Function 0
Function 1
Function 2
Function 3
NOTE: This does not determine the mapping to the PIRQ pins.
Serial Bus Release Number — RO.
