And/Or combination of interrupt events. Default value: 0. Refer to Table 73
6-direction detection function enabled. Default value: 0. Refer to Table 73
Enable interrupt generation on Z high event or on direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request)
Enable interrupt generation on Z low event or on direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request)
Enable interrupt generation on Y high event or on direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
Enable interrupt generation on Y low event or on direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
Enable interrupt generation on X high event or on direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
Enable interrupt generation on X low event or on direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
Content of this register is loaded at boot.
Write operation at this address is possible only after system boot.

Difference between AOI-6D = ‘01’ and AOI-6D = ‘11’.
AOI-6D = ‘01’ is movement recognition. An interrupt is generated when the orientation
moves from an unknown zone to a known zone. The interrupt signal remains for a duration
ODR.
AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation is
inside a known zone. The interrupt signal remains until the orientation is inside the zone.
