Following is a summary and a brief description of the chapters of this manual:

¥

Part I, ÒOverview,Ó provides a high-level description of the MPC8260, describing
general operation and listing basic features.

Ñ Chapter 1, ÒOverview,Ó provides a high-level description of MPC8260 functions

and features. It roughly follows the structure of this book, summarizing the
relevant features and providing references for the reader who needs additional
information.

Ñ Chapter 2, ÒPowerPC Processor Core,Ó provides an overview of the MPC8260

core, summarizing topics described in further detail in subsequent chapters.

Ñ Chapter 3, ÒMemory Map,Ó presents a table showing where MPC8260 registers

are mapped in memory. It includes cross references that indicate where the
registers are described in detail.

¥

Part II, ÒConÞguration and Reset,Ó describes start-up behavior of the MPC8260

Ñ Chapter 4, ÒSystem Interface Unit (SIU),Ó describes the system conÞguration

and protection functions which provide various monitors and timers, and the 60x
bus conÞguration.

Ñ Chapter 5, ÒReset,Ó describes the behavior of the MPC8260 at reset and start-up.

¥

Part III, ÒThe Hardware Interface,Ó describes external signals, clocking, memory
control, and power management of the MPC8260.

Ñ Chapter 6, ÒExternal Signals,Ó shows a functional pinout of the MPC8260 and

describes the MPC8260 signals.
