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, Message 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. Figure 8–1 illustrates these registers.
