messages. Any INTA emulation interrupts already asserted must
be deasserted when this bit is set.
Only affects interrupts generated by the device (PCI INTA from a
PME or Hot Plug event) controlled by this command register. It
does not affect upstream MSIs, upstream PCI INTA-INTD assert
and deassert messages.
Fast Back-to-Back Enable (FB2B):
Not Applicable or Implemented. Hardwired to 0.
