Tmega128具备引导加载支持的用户程序自编程功能(In-System Programming

by On-chipBoot Program)，它提供了一个真正的由MCU本身自动下载和更新（

采用读/写同时"Read-While-Write"进行的方式）程序代码的系统程序自编程更 新的机制。利用AVR的这个功能，可以实现在应用编程（IAP）以及实现系统程 序的远程自动更新的应用。-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.
