Table 66. INT2_CFG_A description (continued)
Enable interrupt generation on Z low event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value lower than preset threshold)
Enable interrupt generation on Y high event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value higher than preset threshold)
Enable interrupt generation on Y low event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value lower than preset threshold)
Enable interrupt generation on X high event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value higher than preset threshold)
Enable interrupt generation on X low event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value lower than preset threshold)
The content of this register is loaded at boot.
A write operation to this address is possible only after system boot.

6-direction movement recognition
AND combination of interrupt events
6-direction position recognition
The 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 while the orientation is inside the zone.
