The Definitive Guide to the ARM Cortex-M0 and Cortex-M0+ Processors, Second Edition explains the architectures underlying ARM's Cortex-M0 and Cortex-M0+ processors and their programming techniques. Written by ARM's Senior Embedded Technology Manager, Joseph Yiu, the book is packed with examples on how to use the features in the Cortex-M0 and Cortex-M0+ processors. It provides detailed information on the instruction set architecture, how to use a number of popular development suites, an overview of the software development flow, and information on how to locate problems in the program code and software porting. This new edition includes the differences between the Cortex-M0 and Cortex-M0+ processors, such as architectural features (e.g., unprivileged execution level, vector table relocation), new chapters on low power designs and the Memory Protection Unit (MPU), and the benefits of the Cortex.
