 * @file main.c
 * @brief Flash8 Click example
 *
 * # Description
 * This library contains API for Flash 8 Click driver.
 * The library using SPI serial interface.
 * The library also includes a function for write and read memory
 * as well as write protection control functions.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SPI module and log UART.
 * After driver initialization and default setting, 
 * involves disabling write protection and hold, 
 * the app writes demo_data string ( mikroE ) starting 
 * from the selected row_address of the 123 ( 0x0000007B ) 
 * and column_address of the 456 ( 0x01C8 ).
 *
 * ## Application Task
 * This is an example that shows the use of a Flash 8 Click board™.
 * The app reads a data string, which we have previously written to memory, 
 * starting from the selected row_address of the 123 ( 0x0000007B ) 
 * and column_address of the 456 ( 0x01C8 ).
 * Results are being sent to the Usart Terminal where you can track their changes.
