Develop data storage and transfer solution with EN25Q80B and MK64FN1M0VDC12

/*!
 * \file main.c
 * \brief Flash Click example
 *
 * # Description
 * This example demonstrates the use (control) of the FLASH memory.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes all necessary peripherals and pins used by Flash click and also
 * initializes uart logger to show results.
 *
 * ## Application Task
 * Executes memory data writing, reading from the memory to verify data writing
 * operation and sector erasing to clear memory.
 *
 * ## Additional Functions
 * - Enter Data / Allows user to enter a desired data.
 * - Process Wait / Makes a delay to wait while some process be done.
