User’s manuals — These books provide details about individual ColdFire implementations and are
intended to be used in conjunction with the ColdFire Programmers Reference Manual.
Data sheets — Data sheets provide specific data 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 an device’s reference manual.
Application notes — These short documents address specific design issues useful to programmers
and engineers working with Freescale Semiconductor processors.
In text, instruction mnemonics are shown in uppercase.
