Indicates whether this PCI Express device is configured as a master.
Reserved
Controls the ability to generate INTx interrupt messages.
0 Enables INTx interrupt messages
1 Disables INTx interrupt messages
Any INTx emulation interrupts already asserted by this device must be deasserted when this bit is set.
Reserved
Controls the reporting of fatal and non-fatal errors detected by the device to the root complex.
0 Disables reporting
1 Enables reporting
Note: The error control and status bits in the command and status registers control PCI-compatible error
Reserved
Controls whether this PCI Express controller responds to parity errors.
0 Parity errors are ignored and normal operation continues.
1 Parity errors cause the appropriate bit in the PCI Express status register to be set. However, note that

0 Disables the ability to generate PCI Express accesses
1 Enables this PCI Express controller to behave as a PCI Express bus master
EP mode: Clearing this bit prevent the device from issuing any memory or I/O transactions. Because MSI
interrupts are effectively memory writes, clearing this bit also disables the ability of the device to issue
MSI interrupts.
RC mode: Clearing this bit disables the ability of the device to forward memory transactions upstream.
This causes any inbound memory transaction to be treated as an unsupported request.
