Advanced Architecture Features
Abstract
This chapter looks at the mode advanced features included in the Cortex-M processors. We examine how to configure the Cortex-M processor to use two stacks and enable privileged and unprivileged operating modes. We also look at the supervisor call, Exclusive Access instructions, and Pend exception. This chapter concludes by looking at how to use the memory protection unit for safety and security applications.
