Registers description
Table 43. INT1_CFG_REG_A description (continued)
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/XDO Enable interrupt generation on X low event or on direction recognition. Default value: 0
WNE
(0: disable interrupt request; 1: enable interrupt request.)
The contents of the INT1_CFG_REG_A register are 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’ is defined as follows:
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 stays for a duration
determined by ODR.
AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation is
inside a known zone. The interrupt signal stays until orientation is inside the zone.
