Configuration Space Signals
The signals in
configuration space registers that the application layer may need to
access.
Configuration traffic class/virtual channel mapping: The application layer uses this
signal to generate a transaction layer packet mapped to the appropriate virtual
channel based on the traffic class of the packet.

Configuration bus device: This signal generates a transaction ID for each transaction
layer packet, and indicates the bus and device number of the MegaCore function.
Because the MegaCore function only implements one function, the function number
of the transaction ID must be set to 000b.

Configuration primary control status register. The content of this register controls the
PCI status.
Configuration dev control status register. See PCI Express specification for details.
Configuration link control status register. See PCI Express specification for details.
