1. Initialize MCU settings, including I/O, Timer, ISR and Serial Port settings.

2. Read EEPROM content to recover monitor settings, including brightness, contrast, color temperature

   and OSD position etc.

3. Initialize system variable, including system flag, OSD timeout counter, burin mode status… etc.

4. Initialize OSD menu variable for user operation

5. Initialize device on the board, now only MST scaler chip will be initialized

6. Check if system is in power off status from first AC power up. If yes, then go to 7, else go to 8.

7. If yes, system will be forced to enter power off status

8. Mode detection

9. Check if input timing has been changed, if yes then go to 10, else go to 11

10. Setup MST scaler for display according input timing

11. OSD handler for OSD operation.

12. Debug handler, only debug only
