Description

Number of

bits

Reset-value

en_slope_x

en_slope_y

en_slope_z

0x0D.5

0x0D.4

0x0D.3

enable slope detection on x-axis

enable slope detection on y-axis

enable slope detection on z-axis

3 “000”

slope_th 0x09[5:2]

define the threshold level of the

slope

1 LSB threshold is 1 LSB of

acc_data

SLOPE_T

H_NUM

SLOPE_TH_I

NIT (“0001”)

slope_dur 0x09[1:0]

define the number of consecutive

slope data points above slope_th

which are required to set the

interrupt

(“00” = 1,”01” = 2,”10” = 3, “11” = 4)

SLOPE_D

UR_NUM

SLOPE_DUR

_INIT (“01”)

slope_filt 0x09.6

defines whether filtered or unfiltered

acceleration data should be used

(evaluated)

(‘0’=unfiltered, ‘1’=filtered)

1 ‘1’

slope_int 0x0C.0

whether slope interrupt has been

triggered

1 ‘0’

slope_first_x

slope_first_y

slope_first_z

whether x-axis has triggered the

interrupt (0=no, 1=yes)

whether y-axis has triggered the

interrupt (0=no, 1=yes)

whether z-axis has triggered the

interrupt (0=no, 1=yes)

3 “000”

slope_sign

global register bit for all interrupts

define the slope sign of the

triggering signal (0=positive slope,

1=negative slope)

1 ‘0’

* For determining the corresponding I

C register address, please refer to figure 2 in chapter 4 (memory map)
