 * \file 
 * \brief FRAM2 Click example
 * 
 * # Description
 * This example performs write & read operation to certain register.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initiazlize device and enable write operation.
 * 
 * ## Application Task  
 * Write value 42 to register 0x10 and check if operation was done properly.
 * 
 * *note:* 
 * data_to_write variable is declared as const, so compiler may warn user 
 * about 'suspisuous pointer conversion'. Note it is the case only with this
 * code snippet but user has freedom to use driver functions as he wishes.
