LIR

1. This bit must be set to 0 for the correct operation of the device.

Table 112. INT_CFG0 register description

INT_CLR_ON_READ

This bit allows immediately clearing the latched interrupts of an event detection upon the read of

the corresponding status register. It must be set to 1 together with LIR. Default value: 0

(0: latched interrupt signal cleared at the end of the ODR period;

1: latched interrupt signal immediately cleared)

SLEEP_STATUS_ON_INT

Activity/inactivity interrupt mode configuration.

If INT1_SLEEP_CHANGE or INT2_SLEEP_CHANGE bits are enabled, drives the sleep status or

sleep change on INT pins. Default value: 0

(0: sleep change notification on INT pins; 1: sleep status reported on INT pins)

SLOPE_FDS

HPF or SLOPE filter selection on wake-up and activity/inactivity functions. Default value: 0

(0: SLOPE filter applied; 1: HPF applied)

LIR

Latched interrupt. Default value: 0

(0: interrupt request not latched; 1: interrupt request latched)

INACT_EN0

0(1)

1. This bit must be set to 0 for the correct operation of the device.

Table 114. INT_CFG1 register description

INTERRUPTS_ENABLE

Enables hardcoded functions

INACT_EN[1:0]

Enables activity/inactivity (sleep) function. Default value: 00

(00: stationary/motion-only interrupts generated, accelerometer and gyroscope do not change;

01: sets accelerometer ODR to 12.5 Hz (low-power mode), gyroscope does not change;

10: sets accelerometer ODR to 12.5 Hz (low-power mode), gyroscope to sleep mode;

11: sets accelerometer ODR to 12.5 Hz (low-power mode), gyroscope to power-down mode)
