Axes remapping for interrupt features
If the sensor orientation is different than described in chapter 8.2 the sensor axis must be remapped
to use the integrated features.
Axes remapping register allows the host to freely map individual axis to the coordinate system of the
used platform. Individual axis can be mapped to any other defined axis. The sign value of the axis can
be also configured. For example x axis can be mapped to –x axis, +y axis, - y axis, +z axis or –z axis.
Similarly other axis also have its own combination.
Note:
The axis remapping does apply only to the data fetched into the Features. The DATA_0 to DATA_13
registers and FIFO are not affected and should be accordingly remapped on the driver level.
Configuration settings:
1. FEATURES_IN.general_settings.axes_remapping.map_x_axis – describes which axis shall
be mapped to x axis.
2. FEATURES_IN.general_settings.axes_remapping.map_x_axis_sign – describes whether the
mapped axis shall be inverted or not to be inverted.
3. FEATURES_IN.general_settings.axes_remapping.map_y_axis – describes which axis shall
be mapped to y axis.
4. FEATURES_IN.general_settings.axes_remapping.map_y_axis_sign – describes whether the
mapped axis shall be inverted or not to be inverted.
5. FEATURES_IN.general_settings.axes_remapping.map_z_axis –describes which axis shall
be mapped to z axis.
6. FEATURES_IN.general_settings.axes_remapping.map_z_axis_sign – describes whether the
mapped axis shall be inverted or not to be inverted.
