LSM6DS3加速度计X/Y/Z轴用户偏移寄存器不能写入？

我尝试使用LSM6DS3的加速度计X / Y / Z轴用户偏移校正寄存器（X_OFS_USR：0x73，Y_OFS_USR：0x74，Z_OFS_USR：0x75）来硬件补偿其加速度计测量以节省我的主机CPU负载，但我发现它们将留在在写入任何非零值（-127~127，如您在DocID028475 Rev 4，2016年6月的规范中的第88-89页中指定）后为零？
有人使用LSM6DS3的内置硬件偏移寄存器并解决了上述问题吗？

另一方面，可以在允许访问嵌入式功能寄存器（FUNC_CFG_ACCESS）之后写入MAG_OFF X / Y / Z，但是它随机地改变，例如，在模块静态指向180度时，在180到206度之间变化。如果我将MAG_OFF X / Y / Z寄存器归零并手动应用偏移补偿（磁力测量 - 偏置），那么补偿方向是正确的并固定在180度而不随意改变！问题来自功能失常的自动温度补偿吗？ （因为我重新读取寄存器，发现在写入具有非零偏移值的MAG_OFF X / Y / Z寄存器后，reg值会随机变化）

  I tried to use LSM6DS3's Accelerometer X/Y/Z-axis user offset correction registers(X_OFS_USR: 0x73, Y_OFS_USR: 0x74, Z_OFS_USR: 0x75) to hardware compensate its accelerometer measures to save my host CPU loading, but I found they will stay at zeros after writing with any non-zero values(-127 ~ 127 as specified at page 88-89 in your specification of DocID028475 Rev 4, June 2016)?  
Have someones used LSM6DS3's built-in hardware offset registers and  solved the above problems?

  On the other side, MAG_OFF X/Y/Z can be written after enabling access to Embedded Function Register (FUNC_CFG_ACCESS), but it randomly changes, e.g. changing between 180 and 206 deg while the module is statically pointed to 180 deg.  If I zero MAG_OFF X/Y/Z registers and manually apply offset compensation(mag measure - bias), then the compensated direction is correct and fixed at 180 deg without random changing!   Does the problem come from a mal-functional auto-temperature-compensated ? (since I re-read registers and found that the reg values will randomly change after writing MAG_OFF X/Y/Z registers with non-zero offset values)
