cute the code and perform all calculations. The CPU is able to access memories, perform
calculations, control peripherals, and execute the program in the flash memory. Interrupt han-
dling is described in a separate section,
Controller” on page
In order to maximize performance and parallelism, the AVR CPU uses a Harvard architecture
with separate memories and buses for program and data. Instructions in the program memory
are executed with single-level pipelining. While one instruction is being executed, the next
instruction is pre-fetched from the program memory. This enables instructions to be executed on
every clock cycle. For a summary of all AVR instructions, refer to
