- Sample CodeThe accompanying demo code, provided in Python, demonstrates how to access and interact with the boot mode on RA8M1 and RA8P1 MCUs. It serves as a practical example for developers to see the boot mode interface in action, showing step-by-step procedures for communication and control. Although targeted at RA8M1 and RA8P1, the code and methodology can be adapted to other RA8 MCU devices by following the guidelines laid out in the application note, thereby accelerating development and reducing errors when working with boot mode features.
