Note:
Register Summary
Writes to unused address space have no affect. Reads from unused address space may
return indeterminate data. Neither reads nor writes cause detrimental effects on device
operation unless specifically documented. Reserved bits within registers must be
written with their reset value unless otherwise stated.
For more information on the conventions the following register summaries adopt, see
Section 7.1, “Overview of Register Descriptions and Summaries” on page 183.
Any programming order dependencies on configuration write values must be handled
by the OS.
The Global Configuration Unit registers materialize in the PCI space.
