controller’s INTx_B signal will be de-asserted. When
cleared, the INTx_B signal may be asserted. Note that this bit does not
affect the generation of MSI’s.

Bus Master Enable: Controls standard PCI Express* bus mastering
capability for Memory and I/O, reads and writes. Note that this bit also
controls MSI generation since MSI’s are essentially Memory writes.
