Register description LSM303D

8.34 IG_CFG2 (34h)
This register contains the settings for the inertial interrupt generator 2.
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 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 until the orientation is inside the zone.
