Figure 3 shows the device configuration in the six different orientation modes. These orientations are defined as the following:
PU = portrait up, LR = landscape right, PD = portrait down, LL = landscape left, back and front side views. There are several
registers to configure the orientation detection and are described in detail in the register setting section.
