You can still drive the xtal-in pin with a clock source
program one of your other microcontrollers to produce a 32kHz clock on
a pin and pump it in to the xtal-in
then rewrite your fuses.

Hi All,
Apologies for the following question which is very OT, but there
is a
good chance you guys can help.
I am using an ATMega32 and inadvertantly programmed the fuse bits
wrong
:-( ... instead of setting
the fuse bits to use a 16 Mhz external crystal as the clock
source, I
programmed the chip to use the low frequency
crystal oscillator setting. Of course now, I can not program the
device
anymore.
Does anybody know if there is any way (other than getting hold of a
32.768 Khz crystal) that I can recover the device ?
Many thanks for any suggestions,
James

Hi you can use one from old digital clock (or new one)
=)
You can also program via the JTAG pins, you do not need an external
clock for that.
The AVRDRAGON is quite cheap, which you can use to re-program the
fuses.
