 * \brief Flash2 Click example
 * 
 * # Description
 * This application demonstrates the process of writing and reading data from Flash 2 click memory.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Flash Driver Initialization, initialization of click by setting mikorBUS to
 * approprieate logic levels, performing global block unlock and chip erase functions.
 * 
 * ## Application Task  
 * Writing data to click memory and displaying the read data via UART.
