About This Manual
This manual is intended to assist the designer who is attempting to implement a solution using the PCI4450 or PCI4451. Much, but not all, of the information contained herein can also be found elsewhere. However, the smaller size of this manual, as well as its organization by topics of primary interest to the hardware designer, make it a much more usable source regarding those problems most likely to be encountered in the design process.
How to Use This Manual
This document contains the following chapters:
Chapter 1, PCI445X Device, provides the designer with information and examples beyond that contained in the data manuals, which will be useful for implementing solutions using the PCI4450 or PCI4451.
Appendix A, Global Reset Only Bits, PME Context Bits contains tabular listings of those register bits that can only be cleared by a global reset, and of those register bits used in conjunction with power management events.
Appendix B, PME and RI Behavior, provides truth tables that explain events and conditions which can wake up a device that has been placed in partially functional state for power conservation.
Appendix C, PCI445X Buffer Types, lists the type of signal buffering used for input and/or output on each terminal of the device.
Notational Conventions
This document uses the following conventions.
Program listings, program examples, and interactive displays are shown in a special typeface similar to a typewriter's. Examples use a bold version of the special typeface for emphasis; interactive displays use a bold version of the special typeface to distinguish commands that you
