Content of this register is loaded at boot.

Write operation at this address is possible only after system boot.

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.
