 * \brief Ata663254 Click example
 * 
 * # Description
 * This application demonstates the use of ATA663254 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the Click driver and enables the Click board.
 * 
 * ## Application Task  
 * Depending on the selected mode, it reads all the received data or sends the desired message
 * each 2 seconds.
