<h3>Media Access Interface</h3>

<p>Since FatFs module is the <em>filesystem layer</em> independent of platforms and storage media, it is completely separated from the physical devices, such as memory card, harddisk and any type of storage device. The storage device control module is <em>not any part of FatFs module</em> and it needs to be provided by implementer. FatFs controls the storage devices via a simple media access interface shown below. Also sample implementations for some platforms are available in the downloads. A function checker for storage device control module is available <a href="res/app4.c">here</a>.</p>
