7.19 INT1_CFG (30h)
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 generate when orientation move from
unknown zone to known zone. The interrupt signal stay for a duration ODR.
AOI-6D = ‘11’ is direction recognition. An interrupt is generate when orientation is inside a
known zone. The interrupt signal stay untill orientation is inside the zone.
