3. Modify the stationary and insert your own code

   There are four files in the new project that most in need of modification: main.c, ISR.h, Flash_config.c and Cpu.c.

   1. Cpu c contains the routine executed before main. Expand the project folder and select Project_Settings -> Startup_Code -> Cpu.c, open this file.
      • 8 MHz internal clock with PLL is used by default, changing CLOCK_CONFIG to choose other clock source.
      • Device run in normal mode (50 MHz system clock) by default, setting STARTUP_FAST_MODE will configure the device to run in fast mode (100 MHz system clock).
      • Device boot from Flash after reset by default, setting ENTER_BOOTLOADER will enable ROM bootloader. ROM bootloader is executed firstly out of reset.
      
   2. Flash_config.c contains a structure variable that configures Bootloader Configuration Area (BCA) and an array variable that configures Flash Configures Field (FCF).
   3. ISR.h contains macros to redefine ISR names. Expand the project folder and select Project_Headers -> ISR.h, open this file, then modify the desired interrupt vector name and add the ISR declaration. The following picture provides an example of PIT0 interrupt.
      
   4. In main.c, delete the unwanted example codes, but keep below two lines.
      
   5. Insert your own codes.
4. Build, compile and run the project as described previously.

The following steps will guide you through cloning the example project with MCUXpresso Config Tool.
