XMEGA uses the 8/16-bit AVR CPU. The main function of the CPU is to ensure correct program
execution. The CPU is able to access memories, perform calculations and control peripherals.
Interrupt handling is described in a separate section, refer to
Multi-level Interrupt Controller” on page 123
In order to maximize performance and parallelism, the AVR uses a Harvard architecture with
separate memories and buses for program and data. Instructions in the program memory are
executed with a single level pipelining. While one instruction is being executed, the next instruc-
tion is pre-fetched from the Program Memory. This concept enables instructions to be executed
in every clock cycle. For the summary of all AVR instructions refer to
