Register description LIS2DH12
42/53 DocID025056 Rev 6
A write operation to this address is possible only after system boot.
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 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 while the orientation is inside the zone.
8.20 INT1_SRC (31h)
Interrupt 1 source register. Read-only register.
Reading at this address clears the INT1_SRC (31h) IA bit (and the interrupt signal on the
INT1 pin) and allows the refresh of data in the INT1_SRC (31h) register if the latched option
was chosen.
