+/**********************************************************************
+ *
+ * 实验名称：FLASH擦写
+ * 实验平台：NV32开发板
+ * 板载芯片：NV32F100FL64E
+ * 实验效果：使用FLASH模拟EEPROM,实现字节的编程
+ * 实验说明：NV32F100x系列芯片不带有硬件EEPROM，
+ *					除128K FLASH空间外，还带有5K的NVR空间:0x0040_0000-0x0040_13FF
+ *					操作与前128K一致，不过该区域在执行整片擦除时不会被擦除，可供用户用来作为数据存储区域
