 * This example demonstrates the use of EERAM 3 click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Writes a desired number of bytes to the memory and then verifies that it's written correctly
 * by reading from the same memory location and displaying the memory content on the USB UART.
