PXR40RM Datasheet, PDF (34/1434 Pages) Freescale Semiconductor, Inc – PXR40 Microcontroller

• Computer Organization and Design: The Hardware/Software Interface, Second Edition, David A.
Patterson and John L. Hennessy.
Power Architecture documentation
Power Architecture documentation is available from the sources listed on the back cover of this manual,
as well as our web site, http://www.freescale.com/powerpc.
• Reference manuals (formerly called user’s manuals)—These books provide details about
individual PowerPC implementations and are intended to be used in conjunction with the PowerPC
Programmers Reference Manual.
• Addenda/errata to reference manuals—Because some processors have follow-on parts, an
addendum is provided that describes the additional features and functionality changes. Also, if
mistakes are found within a reference manual, an errata document may be issued before the next
published release of the reference manual. These addenda/errata are intended for use with the
corresponding reference manuals.
• Data sheets—Data sheets provide specific information regarding pin-out diagrams, bus timing,
signal behavior, and AC, DC, and thermal characteristics, as well as other design considerations.
• Product briefs—Each device has a product brief that provides an overview of its features. This
document is roughly equivalent to the overview (Chapter 1) of a device’s reference manual.
• Application notes—These short documents address specific design issues useful to programmers
and engineers working with Freescale Semiconductor processors.
Additional literature is published as new processors become available. For a current list of PowerPC
documentation, refer to http://www.freescale.com/powerpc.
Conventions
This document uses the following notational conventions:
cleared/set
When a bit takes the value zero, it is said to be cleared; when it takes a value of
one, it is said to be set.
reserved
When a bit or address is reserved, it should not be written. If read, its value cannot
be not guaranteed. Reading or writing to reserved bits or addresses may cause
unexpected results.
MNEMONICS
In text, instruction mnemonics are shown in uppercase.
mnemonics
In code and tables, instruction mnemonics are shown in lowercase.
italics
Italics indicate variable command parameters.
Book titles in text are set in italics.
0x0
Prefix to denote hexadecimal number
0b0
Prefix to denote binary number
REG[FIELD]
Abbreviations for registers are shown in uppercase. Specific bits, fields, or ranges
appear in brackets. For example, RAMBAR[BA] identifies the base address field
in the RAM base address register.
