INTERRUPTS_

ENABLE

Enable basic interrupts (6D/4D, free-fall, wake-up, tap, inactivity). Default value: 0

(0: interrupt disabled; 1: interrupt enabled)

INACT_EN[1:0]

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

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

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

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

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

TAP_THS_Y_[4:0]

Y-axis tap recognition threshold. Default value: 0

1 LSB = FS_XL / (25)
