In most cases, application code can be written in C or other high-level languages. However, a basic understanding of the instruction set supported by Cortex-M processors helps developers choose the appropriate Cortex-M processor for specific applications. The instruction set architecture (ISA) is part of the processor architecture, and Cortex-M processors can be divided into several … Read more
