AVR microcontrollers use a Harvard architecture. What do you think that means?
Does it mean the program and data memory are separate?
That's correct! This separation allows faster execution of instructions. Can you think of any advantages of this method?
Maybe it can read instructions while processing data at the same time?
Great insight! This allows for more efficient processing, which is critical in embedded applications!
