 * @file main.c
 * @brief Flash 10 Click example
 *
 * # Description
 * This example demonstrates the use of Flash 10 Click board by writing specified data to
 * the memory and reading it back.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and checks the communication by reading and verifying the device ID.
 *
 * ## Application Task
 * 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 on the USB UART.
 * The whole 4KB block of memory that contains the STARTING_ADDRESS will be erased before writing data.
