8 Register Maps

8.1 Classic PCI Configuration Space

8.1.1 The PCI Configuration Map

The programming model of the TUSB73X0 USB 3.0 Host Controller is compliant to the standard PCI device

programming model. The PCI configuration map uses the type 0 PCI header.

Sticky bits, which are reset by a global reset (GRST) or the internally-generated power-on-reset, and bits that

are reset by a PCI Express reset (PERST), a GRST, or the internally generated power-on-reset are indicated as

such.
