The interrupt system of Cortex-M3 is central to its implementation of real-time performance and efficient task scheduling, integrating advanced features of the ARMv7-M architecture. In certain application scenarios (such as critical sections), interrupt masking operations are often required to prevent the program from being interrupted during specific operations, similar to atomic operations. Therefore, interrupt masking … Read more
