 251 <p><b>NAND API</b></p>
 252 <p>The following header files define the Application Programming Interface (API) for the NAND interface:</p><ul>
 253 <li><b>Driver_NAND.h</b> : Driver API for NAND Flash Device Interface</li>
 254 </ul>
 255 <p>The driver implementation is a typical part of the Device Family Pack (DFP) that supports the peripherals of the microcontroller family.</p>
 256 <p>NAND Flash is organized in pages, grouped into blocks as the smallest erasable unit. The addressing of data is achieved by <code>byte_address = block * block_size + page_in_block * page_size + offset_in_page</code>. In terms of this NAND API blocks and pages are referred to as <code>row</code> and the byte offset within the page as <code>col</code>. Thus one can calculate the <code>byte_address = row * page_size + col</code>. The parameters <code>page_size</code> and <code>block_size</code> are device specific and must be handled by the driver user appropriately.</p>
 257 <p><b>Driver Functions</b></p>
 258 <p>The driver functions are published in the access struct as explained in <a class="el" href="theoryOperation.html#DriverFunctions">Common Driver Functions</a></p><ul>
