PCI Bus Interface

The PCI interface is compatible with the PCI Local Bus Specification, Rev. 2.3. It is beyond the scope of

this manual to document the intricacies of PCI. This chapter describes the PCI controller and provides a

basic description of the PCI bus operations. The specific emphasis is directed at how this device

implements the PCI specification. Designers of systems incorporating PCI devices should refer to the

respective specifications for a thorough description of the PCI buses.

The PCI controller acts as a bridge between the PCI interface and the CSB. The I/O sequencer buffers the

Introduction

MPC8313E PowerQUICC™ II Pro Integrated Processor Family Reference Manual, Rev. 2

Much of the available PCI literature refers to a 16-bit quantity as a WORD

and a 32-bit quantity as a DWORD. Because this is inconsistent with the

terminology in this manual, the terms ‘word’ and ‘double word’ are not used

in this chapter. Instead, the number of bits or bytes indicates the exact

is a high-level block diagram of the PCI controller.
