Table 63. IG_CFG1 register description
And/Or combination of interrupt events. Default value: 0.
Refer to Table 64
6-direction detection function enabled. Default value: 0.
Refer to Table 64
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.)

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