Well, you have 2 choices about where the interrupt vector table can go. Search the datasheet for the IVSEL bit. It allows the ISRs to be at the beginning of the bootloader (in case you want an interrupt driven bootloader), or at the beginnning of the application. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
