Table 134. WAKE_UP_THS register description

SINGLE_DOUBLE_TAP

Single/double-tap event enable. Default: 0

(0: only single-tap event enabled;

1: both single and double-tap events enabled)

USR_OFF_ON_WU

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

wakeup function.

WK_THS[5:0]

Threshold for wakeup: 1 LSB weight depends on WAKE_THS_W in WAKE_UP_DUR (5Ch). Default

value: 000000

Table 136. WAKE_UP_DUR register description

FF_DUR5

Free fall duration event. Default: 0

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

configuration.

1 LSB = 1 ODR_time

WAKE_DUR[1:0]

Wake up duration event. Default: 00

1LSB = 1 ODR_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
