 * @file main.c
 * @brief Flash 12 Click example
 *
 * # Description
 * This example demonstrates the use of Flash 12 Click board 
 * by writing specified data to the memory and reading it back.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of SPI module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The demo application writes a desired number of bytes to the memory 
 * and then verifies if it is written correctly by reading 
 * from the same memory location and displaying the memory content.
 * Results are being sent to the UART Terminal, where you can track their changes.
