About this book
This book is a generic user guide for devices that implement the ARM Cortex-M4 processor.
Implementers of Cortex-M4 designs make a number of implementation choices, that can affect
the functionality of the device. This means that, in this book:
• some information is described as implementation-defined
• some features are described as optional.
In this book, unless the context indicates otherwise:
Processor Refers to the Cortex-M4 processor, as supplied by ARM.
Device Refers to an implemented device, supplied by an ARM partner, that incorporates
a Cortex-M4 processor. In particular, your device refers to the particular
implementation of the Cortex-M4 that you are using. Some features of your
device depend on the implementation choices made by the ARM partner that
made the device.
