AVRDUDE Attiny84 Fuses 
The ATtiny84 uses three fuse bytes that configure clock rate and special features on-board the chip. 
The fuses are known as "Fuse Low Byte", "Fuse High Byte", and "Fuse Extended Byte". 
"Fuse Low Byte" configures the processor's clock source, start-up timing, clock output, and internal divide by 8 function.
