About Code Examples

This documentation contains simple code examples that briefly show how to use various parts

of the device. These code examples assume that the part specific header file is included

before compilation. Be aware that not all C compiler vendors include bit definitions in the

header files and interrupt handling in C is compiler dependent. Please confirm with the C com-

piler documentation for more details.

4.3 AVR CPU Core

4.3.1 Overview

This section discusses the AVR® core architecture in general. The main function of the CPU

core is to ensure correct program execution. The CPU must therefore be able to access mem-

ories, perform calculations, control peripherals, and handle interrupts.
