Difference between AOI-6D = ‘01’ and AOI-6D = ‘11’.

AOI-6D = ‘01’ is movement recognition. An interrupt is generated when orientation moves

from unknown zone to 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.

Table 50. INT2_CFG_A description

AOI

AND/OR combination of interrupt events. Default value: 0

(see Table 51)

6D 6-direction detection function enabled. Default value: 0 (refer to Table 51)

ZHIE

Enable interrupt generation on Z high event. Default value: 0

(0: disable interrupt request,

1: enable interrupt request on measured accel. value higher than preset threshold)

ZLIE

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)

YHIE

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)

YLIE

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)

XHIE

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)

XLIE

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)
