Introduction

This application note is a document to assist users in converting designs between tinyAVR® 1-series and tinyAVR 0-series, and gives an overview of the functional differences between these families. Note that there may be differences in errata and electrical characteristics that are not covered in this application note. Please refer to the specific data sheets for details.

Register names, bit names, and bit group names can be expected to be the same for both families, when present.
