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.

Usually i program CKOPT only (check CKOPT, uncheck all 
others). I use ATmega8515. I made a mistake once using 
ponyprog. 1=programmed, 0=unprogrammed, right? 
Unfortunately in ponyprog there are no 1's or 0's. They 
use checkmarks. Checked=0, not_checked=1. Most of the 
times this confuses me. So, be careful when using them.

And dont fully believe what i say. Check the datasheets 
again, please. OK?

Regards,
Irfan.
