I am a newbie and am wondering:
1. What is a fuse?
2. When do I need to modify fuses?
3. How to I modify fuses?
I am using an atmega 32A and have been through the entire manual on this device and have found many references to fuses but no details on the above questions. Any chance you can fill me in? I am planning to use an external oscillator, do I need to modify fuse settings to make this works as an external clock?
Many thanks for your help, Dave
