* - File              : Self_programming_main.c
* - Compiler          : IAR EWAVR 2.28a / 3.10c and newer
*
* - Support mail      : avr@atmel.com
*
* - Supported devices : This example is written for ATmega128.
*
* - AppNote           : AVR106 - C functions for reading and writing
*                       to flash memory.
*
* - Description       : The file contains an example program using the Flash R/W
*                       functions provided with the files Self_programming.h /
*                       Self_programming.c . The program should be compiled using
*                       a linker file (*.xcl) that is configured to place the
*                       entire program code into the Boot section of the Flash memory.
*                       Please refer to the application note document for more
*                       information.
