Utilization of AVR memory space

Introduction

This Technical Note document describes modified Harvard architectures as used by different Atmel AVR microcontroller versions, and what data that is put in which segment.

Example

__flash int fi = 1; // fi will end up in the flash code segment

Note: For devices that have unified address space as Atmega4809, ATtiny804 etc.. using the const keyword gives faster and smaller references that __flash.
