Tmega128 with boot loader program to support user self-programming function (In-System Programming by On-chipBoot Program), which provides a true by the MCU to automatically download and update itself (in a read/write both " Read-While-Write" out of the way) system program code update mechanism for self-programming. This feature by using the AVR can be achieved in the Application Programming (IAP) program and the realization of the remote system automatically updates the application.
