使用MB85AS8MT和MK64FN1M0VDC12实现速度、效率和数据密度的完美平衡

 * @file main.c
 * @brief ReRAM2 Click example
 *
 * # Description
 * This library contains API for ReRAM 2 Click driver.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes SPI driver and log UART.
 * After driver initialization the app set default settings, 
 * performs device wake-up, check Device ID,
 * set Write Enable Latch command and write demo_data string ( mikroE ), 
 * starting from the selected memory_addr ( 1234 ).
 *
 * ## Application Task
 * This is an example that demonstrates the use of the ReRAM 2 Click board™.
 * In this example, we read and display a data string, which we have previously written to memory, 
 * starting from the selected memory_addr ( 1234 ).
 * Results are being sent to the Usart Terminal where you can track their changes.
