The AVR architecture is a huge topic in itself. I will just provide a general picture of how the AVR microcontroller works. The AVR uses a Harvard architecture thus it has separate memories and buses for program and data. Instructions in the program memory are executed with a single level pipelining. While one instruction is … Read more
