10 degrees
The Z threshold for each direction can also be adjusted, as shown in Figure 10. This has the
effect of altering the angle relative to the Z axis which causes the orientation state to change.
Figure 11 shows an example of setting the UD_Z_TH and RL_Z_TH registers to different
values, as well as setting the UD_X_TH and RL_Y_TH registers to different values. However
for most applications the same value should be written to both registers in both cases.
