Table 149. WAKE_UP_THS register description

SINGLE_DOUBLE_TAP

Enables single/double-tap event. Default value: 0

(0: only single-tap event enabled;

1: both single and double-tap events enabled)

USR_OFF_ON_WU

Drives the low-pass filtered data with user offset correction (instead of high-pass filtered data) to the

wake-up and the activity/inactivity functions. Default value: 0

WK_THS_[5:0]

Wake-up threshold. The resolution of the threshold depends on the value of

WU_INACT_THS_W_[2:0] in the WAKE_UP_DUR (5Ch) register. Default value: 000000

Table 151. WAKE_UP_DUR register description

FF_DUR_5

Free-fall duration event. Default: 0

For the complete configuration of the free-fall duration, refer to FF_DUR_[4:0] in the FREE_FALL (5Dh)

configuration.

1 LSB = 1/ODR_XL time

WAKE_DUR_[1:0]

Wake-up duration event. Default: 00

1 LSB = 1/ODR_XL time

WAKE_THS_W

Weight of 1 LSB of wakeup threshold. Default: 0

(0: 1 LSB = FS_XL / (26);

1: 1 LSB = FS_XL / (28) )

SLEEP_DUR_[3:0]

Duration to go in sleep mode. Default value: 0000 (this corresponds to 16 ODR)

1 LSB = 512/ODR_XL time
