INT1_DURATION (33h)

D6 - D0 bits set the minimum duration of the Interrupt 2 event to be recognized. Duration

steps and maximum values depend on the ODR chosen.

Duration time is measured in N/ODR, where N is the content of the duration register.

INT2_CFG description

AOI

AND/OR combination of interrupt events. Default value: 0.

(See table below)

6 direction detection function enabled. Default value: 0. Refer to Table 60, "Interrupt

mode"

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)
