Before discussing all the addressing/configuration aspects of the Intel
®
41210 Serial to Parallel
PCI Bridge (also called the 41210 Bridge or the 41210), this section provides a brief summary of
the addressable spaces within the 41210 PCI Express*-to-PCI Bridges (functions 0 and 2), the
corresponding access mechanism, and a description of when they are applicable. A detailed
description of each of these spaces follows in the later chapters.
