1.3 Generating the Code
After configuring the peripherals, click Generate under Resource Management [MCC].
Note: The generated code will add files and folders to the 32-bit MCC
            Harmony project. In the generated code, notice the Peripheral Library files generated
            for Real-Time Clock (RTC), External Interrupt Controller (EIC), and PORT peripherals in
            the Secure project while SERCOM3 (as USART), DMA peripherals in the Non-Secure project.
            MCC also generates main.c files in both Secure and Non-Secure Projects.
        Note: The MCC provides an option to change the generated file
            name, and if this option is not used, by default, the file name main.c is
            generated.
