D7:F0-3 Thunderbolt PCI Express* Controller Registers Registers
This chapter documents the registers of the Thunderbolt PCIe devices.
The Thunderbolt device contains multiple PCIe controller devices:
• Bus 0, Device 7, Function 0 (TBT_PCIe0)
• Bus 0, Device 7, Function 1 (TBT_PCIe1)
• Bus 0, Device 7, Function 2 (TBT_PCIe2)
• Bus 0, Device 7, Function 3 (TBT_PCIe3)
The specified function number assignment is applicable under a single segment PCIe configuration space programming. Please refer to Volume 1 of this document for other programming options.
Note: Register default values are taken from device TBT_PCIe0 only. Consult Volume 1 of this document for Device IDs.
