Root Port TLP Data Registers
The TLP data registers provide a mechanism for the Application Layer to specify data that the Root Port
uses to construct Configuration TLPs, I/O TLPs, and single dword Memory Reads and Write requests.
The Root Port then drives the TLPs on the TLP Direct Channel to access the Configuration Space, I/O
space, or Endpoint memory.
