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 generate when orientation move from
unknown zone to known zone. The interrupt signal stay for a duration ODR.
AOI-6D = ‘11’ is direction recognition. An interrupt is generate when orientation is inside a
known zone. The interrupt signal stay until orientation is inside the zone.

Enable interrupt generation on Z low event or on Direction recognition. Default
value: 0 (0: disable interrupt request;1: enable interrupt request)

YUPE
Enable interrupt generation on Y high event or on Direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
YLIE/
YDOWNE
Enable interrupt generation on Y low event or on Direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
XHIE/
XUPE
Enable interrupt generation on X high event or on Direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
XLIE/XDOWNE Enable interrupt generation on X low event or on Direction recognition. Default
value: 0 (0: disable interrupt request; 1: enable interrupt request.)
