    Will help you out, depending upon the avr controller part number fuse bits are set. Kindly provide the AVR controller part number for solution, also let me know if you are using JTAG to program the controller. If you have JTAG, fuses can be configured through AVR Studio IDE.

     

    A word of caution. Playing around with fuse settings is risky, as long as you don’t take special care. Wrong fuse settings may completely disable the device.
