 209 <p>Driver API for Flash Device Interface (Driver_Flash.h) </p>
 210 <p><a href="http://en.wikipedia.org/wiki/Flash_memory" target="_blank">Flash devices</a> based on NOR memory cells are the preferred technology for embedded applications requiring a discrete non-volatile memory device. The low read latency characteristic of these Flash devices allow a direct code execution (<a href="http://en.wikipedia.org/wiki/Execute_in_place" target="_blank">XIP</a>) and data storage in a single memory product.</p>
 211 <p><b>Flash API</b></p>
 212 <p>The Flash API provides a generic API suitable for Flashes with NOR memory cells independent from the actual interface to the MCU (memory bus, SPI, ...). <a href="http://en.wikipedia.org/wiki/Flash_memory#Serial_flash" target="_blank">SPI</a> flashes are typically not named NOR flashes but have usually same flash cell properties.</p>
 213 <p>The following header files define the Application Programming Interface (API) for the Flash interface:</p><ul>
 214 <li><b>Driver_Flash.h</b> : Driver API for Flash Device Interface</li>
 215 </ul>
 216 <p><b>Driver Functions</b></p>

 339 <p>Stores the characteristics of a Flash device. This includes sector layout, programming size and a default value for erased memory. This information can be obtained from the Flash device datasheet and is used by the middleware in order to properly interact with the Flash device.</p>
 340 <p>Sector layout is described by specifying the <em>sector_info</em> which points to an array of sector information (start and end address) and by specifying the <em>sector_count</em> which defines the number of sectors. The element <em>sector_size</em> is not used in this case and needs to be <em>0</em>. Flash sectors need not to be aligned continuously. Gaps are allowed in the device memory space in order to reserve sectors for other usage (for example application code).</p>
 341 <p>When the device has uniform sector size than the sector layout can be described by specifying the <em>sector_size</em> which defines the size of a single sector and by specifying the <em>sector_count</em> which defines the number of sectors. The element <em>sector_info</em> is not used in this case and needs to be <em>NULL</em>.</p>
 342 <p>The smallest programmable unit within a sector is specified by the <em>program_unit</em>. It defines the granularity for programming data.</p>
 343 <p>Optimal programming page size is specified by the <em>page_size</em> and defines the amount of data that should be programmed in one step to achieve maximum programming speed.</p>
 344 <p>Contents of erased memory is specified by the <em>erased_value</em> and is typically <em>0xFF</em>. This value can be used before erasing a sector to check if the sector is blank and erase can be skipped. </p>
