FF_WU_DURATION_1 (33h)

Duration register for Free-Fall/Wake-Up interrupt 1. Duration step and maximum value

depend on the ODR chosen. Step 2.5 msec, from 0 to 637.5 msec if ODR=400Hz, else step

10 msec, from 0 to 2.55 sec when ODR=100Hz. The counter used to implement duration

function is blocked when LIR=1 in configuration register and the interrupt event is verified

AOI

And/Or combination of Interrupt events. Default value: 0

(0: OR combination of interrupt events; 1: AND combination of interrupt events)

LIR

Latch Interrupt request into FF_WU_SRC reg with the FF_WU_SRC reg cleared by

reading FF_WU_SRC_2 reg. Default value: 0

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

ZHIE

Enable interrupt generation on Z high event. Default value: 0

(0: disable interrupt request;

1: enable interrupt request on measured accel. value higher than preset threshold)

ZLIE

Enable interrupt generation on Z low event. Default value: 0

(0: disable interrupt request;

1: enable interrupt request on measured accel. value lower than preset threshold)

YHIE

Enable interrupt generation on Y high event. Default value: 0

(0: disable interrupt request;

1: enable interrupt request on measured accel. value higher than preset threshold)

YLIE

Enable interrupt generation on Y low event. Default value: 0

(0: disable interrupt request;

1: enable interrupt request on measured accel. value lower than preset threshold)

XHIE

Enable interrupt generation on X high event. Default value: 0

(0: disable interrupt request;

1: enable interrupt request on measured accel. value higher than preset threshold)

XLIE

Enable interrupt generation on X low event. Default value: 0

(0: disable interrupt request;

1: enable interrupt request on measured accel. value lower than preset threshold)
