3.8.2.6 Enabling (disabling) for each axis
Any-motion detection can be enabled (disabled) for each axis separately by writing ´1´ (´0´)
to bits AM_X_AXIS, AM_Y_AXIS, AM_Z_AXIS in the GYR_INT_SETTING register. The
criteria for any-motion detection are fulfilled and the Any-Motion interrupt is generated if the
slope of any of the enabled axes exceeds the threshold GYR_AM_THRES for [Slope
Samples+1]*4 consecutive times. As soon as the slopes of all enabled axes fall or stay below
this threshold for [Slope Samples +1]*4 consecutive times the interrupt is cleared unless
interrupt signal is latched.
3.8.2.7 Axis of slope / any motion interrupt
The interrupt status is stored in bit GYRO_AM in the INT_EN register. The Any-motion
interrupt supplies additional information about the detected slope.
