YHIE/
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.)
The content of this register is loaded at boot.
A write operation at this address is possible only after system boot.

Interrupt mode
0
0 OR combination of interrupt events
0
1 6 direction movement recognition
1
0 AND combination of interrupt events
1
1 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 “unknown zone” to “known zone”. The interrupt signal remains for an ODR
duration.
AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation is
inside a “known zone”. The interrupt signal remains until orientation is within the zone.
