HI! (mega8535 or mega16 ) I used external clock and read fuse bits all clear.(IN PONY means all ones)!!!(in contrast to data sheet). Then for crytal (7.3728MHZ)I did like this : 11110(ckel3...1=1,ckopt=1). but it didn't answer me at all(devic missing)!!! What should I do to use a crystal(7.3728MHZ). Please guide me! Thank you.
