orient_hyst<2:0>: sets the hysteresis of the orientation interrupt; 1 LSB corresponds to 62.5 mg
irrespective of the selected g-range
orient_blocking<1:0>:
selects the blocking mode that is used for the generation of the
orientation interrupt. The following blocking modes are available:
´00b´ no blocking,
´01b´ theta blocking or acceleration in any axis > 1.5g,
´10b´ ,theta blocking or acceleration slope in any axis > 0.2 g or
acceleration in any axis > 1.5g
´11b´ theta blocking or acceleration slope in any axis > 0.4 g or
acceleration in any axis > 1.5g and value of orient is not stable for
at least 100ms
orient_mode<1:0>: sets the thresholds for switching between the different orientations. The
settings: ´00b´ symmetrical, ´01b´ high-asymmetrical, ´10b´ low-
asymmetrical, ´11b´ symmetrical.
