11.21 UD_X_TH: UP/DOWN X AXIS THRESHOLD REGISTER
This 8-bit unsigned value is an offset that is added to the magnitude of the X-axis
accelerometer measurement. The range of the offset is 0g to 0.747g; the resolution is
approximately 2.9mg/bit. See also Section 9.2 Portrait/Landscape.
Increasing this value in conjunction with the RL_Y_TH: Right/Left Y Axis Threshold Register
widens the deadband in portrait /landscape detection.
For most applications, the same value should be written to both registers.
