/// \unit
///
/// !!!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().
/// -# Retrieves and returns the At45 current using AT45D_GetStatus().
