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.

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.
