mpu9250 CYCLE模式数据读取问题

等风来123

最近在使用9250的三轴加速度计采集加速度时，采用CYCLE模式降低功耗，相同的程序相同的姿态下，CYCLE模式下采集的数据只有几百，退出这个模式，采集的数据有几万大小。求各位吧友帮忙看看。

在最后一张图片里提到，
The MPU-9250 can be put into Accelerometer Only Low Power Mode using the following steps:
(i) Set CYCLE bit to 1
(ii) Set SLEEP bit to 0
(iii) Set TEMP_DIS bit to 1
(iv) Set DIS_XG, DIS_YG, DIS_ZG bits to 1
The bits mentioned in the steps (i) to (iii) can be found in Power Management 1 register (Register 107).
In this mode, the device will power off all devices except for the primary I2C interface, waking only the accelerometer at fixed intervals to take a single measurement.
但是第三步的寄存器在寄存器组里没有见到。。。。
