使用MR25H256和STM32L073RZ实现同类最佳的长数据保持非易失性存储器

 * \file 
 * \brief MRAM Click example
 * 
 * # Description
 * This example writes and reads from the Mram Click and displays it on the terminal.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes click driver.
 * 
 * ## Application Task  
 * Writes 10 bytes of buffer data in memory with start address 0x0001. Then reads
 * 10 bytes from memory with start address 0x0001 and shows result on USB UART.
