Freescale Semiconductor PowerQUICC MPC885 Reference Manual page 89

• User's manuals—These books provide details about individual implementations and are intended
for use with the Programming Environments Manual.
• Addenda/errata to user's manuals—Because some processors have follow-on parts an addendum
is provided that describes the additional features and functionality changes. These addenda are
intended for use with the corresponding user's manuals.
• Hardware specifications—Hardware specifications provide specific data regarding bus timing,
signal behavior, and AC, DC, and thermal characteristics, as well as other design considerations.
Separate hardware specifications are provided for each part described in this book.
• Technical summaries—Each device has a technical summary that provides an overview of its
features. This document is roughly the equivalent to the overview (Chapter 1) of an
implementation's user's manual.
• The Programmer's Reference Guide for the PowerPC Architecture: MPCPRG/D—This concise
reference includes the register summary, memory control model, exception vectors, and the
PowerPC instruction set.
• The Programmer's Pocket Reference Guide for the PowerPC Architecture:
MPCPRGREF/D—This foldout card provides an overview of PowerPC registers, instructions, and
exceptions for 32-bit implementations.
• Application notes—These short documents address specific design issues useful to programmers
and engineers working with Freescale processors.
Additional literature is published as new processors become available. For a current list of documentation,

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

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
register.
x In certain contexts, such as in a signal encoding or a bit field, indicates a don't
care.
