3.5.2 Accelerometer configuration
The fusion outputs of the BNO055 are tightly linked with the accelerometer sensor settings.
Therefore the configuration possibilities are restricted when running in any of the fusion
operating modes. The accelerometer configuration can be changed by writing to the
ACC_Config register, Table below shows different Accelerometer configurations

The accelerometer sensor operation mode is not configurable by user when BNO power
mode is configured as low power mode. BNO rewrites the user configured value to Normal
mode when switching from config mode to any BNO operation mode. This used to achieve
the BNO low power mode performance.
