///
/// This directory contains one module for each supported Atmel evaluation kit.

/// Each module provides the necessary definitions and methods for using the

///
/// !!!Contents
/// Each board subdirectory contains board- and chip-dependant files to provide

/// - etc.
///
/// Please refer to the documentation of each directory for more in-depth

///
/// !!!Purpose
///
/// The AT45 Dataflash driver is based on the corresponding AT45 driver.
/// A AT45 instance has to be initialized using the Dataflash levle function
/// AT45_Configure(). AT45 Dataflash can be automatically detected using
/// the AT45_FindDevice() function. Then AT45 dataflash operations such as
/// read, write and erase DF can be launched using AT45_SendCommand function
/// with corresponding AT45 command set.
///
/// !!!Usage
///
/// -# Reads data from the At45 at the specified address using AT45D_Read().
/// -# Writes data on the At45 at the specified address using AT45D_Write().
/// -# Erases a page of data at the given address using AT45D_Erase().
/// -# Poll until the At45 has completed of corresponding operations using
/// AT45D_WaitReady().
