Description

INT_EN_ASLP

Auto-SLEEP/WAKE Interrupt Enable

0 interrupt is disabled (default)

1 interrupt is enabled

Note: The corresponding functional block interrupt enable

bit enables the functional block to route its event

detection flags to the system’s interrupt controller.

The interrupt controller routes the enabled

functional block interrupt to the INT1 or INT2 pin.

INT_EN_LNDPRT

Orientation (Landscape/Portrait) Interrupt Enable

INT_EN_FF_MT

Freefall/Motion Interrupt Enable

INT_EN_DRDY

Data Ready Interrupt Enable
