Architecture Documentation

Architecture documentation is organized in the following types of documents:

•

Manuals—These books provide details about individual implementations of the PowerPC

architecture and are intended to be used with the Programming Environments Manual. These

include the G2 Core Reference Manual (Freescale order #: G2CORERM).

•

Programming environments manuals—These books provide information about resources defined by

the PowerPC architecture that are common to processors that implement the PowerPC architecture. The

two versions include one that describes the functionality of the combined 32- and 64-bit architecture

models and one that describes only the 32-bit model. The MPC8280 adheres to the 32-bit architecture

definition.

— Programming Environments Manual for 32-Bit Implementations of the PowerPC Architecture

(Freescale order #: MPCFPE32B)

•

The Programmer’s Pocket Reference Guide for the PowerPC Architecture:

MPCPRGREF/D—This guide provides an overview of registers, instructions, and exceptions for

32-bit implementations.

•

Application notes—These short documents contain useful information about specific design issues

useful to programmers and engineers working with Freescale’s processors.

Conventions

This document uses the following notational conventions:

Bold entries in figures and tables showing registers and parameter RAM should

be initialized by the user.

mnemonics

Instruction mnemonics are shown in lowercase bold.

italics

Italics indicate variable command parameters, for example, bcctrx.

Book titles in text are set in italics.

0x0

Prefix to denote hexadecimal number

0b0

Prefix to denote binary number

rA, rB

Instruction syntax used to identify a source GPR

Instruction syntax used to identify a destination GPR

REG[FIELD]

Abbreviations or acronyms for registers or buffer descriptors are shown in

uppercase text. Specific bits, fields, or numerical ranges appear in brackets. For

example, MSR[LE] refers to the little-endian mode enable bit in the machine state

In certain contexts, such as in a signal encoding or a bit field, indicates a don’t

care.

Used to express an undefined numerical value

NOT logical operator
