Overview

All Atmel AVR XMEGA devices use the 8/16-bit AVR CPU. The main function of the CPU is to execute 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 handling is described in a separate section, “Interrupts and Programmable

Multilevel Interrupt Controller” on page 112.

Architectural Overview

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 “Instruction Set Summary” on page

343. For details of all AVR instructions, refer to http://www.atmel.com/avr.
