<p>Program the fuse bits of an ATmega128 (disable M103 compatibility,
|
|
enable high speed external crystal, enable brown-out detection, slowly
|
|
rising power). Note since we are working with fuse bits the -u (unsafe)
|
|
option is specified, which allows you to modify the fuse bits. First
|
|
display the factory defaults, then reprogram:
