常见问题解答
IT1181FN-48B芯片的Xor和Mix参数对数据恢复有何影响？
在IT1181FN-48B的布局参数中，Xor 6771_256和Mix Input Order 0是关键的算法设置。Xor值用于处理数据位翻转，而Mix顺序则决定数据混合方式。正确设置这些参数能确保从芯片中提取的原始数据被正确重组，否则恢复出的文件可能损坏或无法识别。实际恢复时需根据芯片型号匹配这些值。
如何理解IT1181的Block Pair和Divide Field参数？
Block Pair（如Block 0x200000）指定了数据块配对的大小，而Divide Field（如Block Number Value 0x20）用于分割块编号字段。这些参数定义了芯片内部数据存储的物理逻辑结构，帮助恢复工具正确识别每个数据块的地址和归属。调整不当会导致数据读取偏移，因此必须按芯片规格书或经验值设置。
IT1181芯片的Page和Block Size参数在恢复中起什么作用？
Page 0x2000和Block Size 0x400000等参数定义了芯片的存储粒度。Page是最小读写单位，Block是擦除单位。恢复时，工具需按此粒度读取原始数据，并配合Image Cut（如0x3ff000）来裁剪有效区域。错误设置会导致读取越界或遗漏数据，所以需严格匹配芯片的物理参数。
