Table 153. PEDO_THS_REG register description
This bit sets the internal full scale used in pedometer functions. Using this bit,
saturation is avoided (e.g. FAST walk).
0: internal full scale = 2 g.
1: internal full scale 4 g (device full_scale @CTRL1_XL must be ≥ 4 g, otherwise
internal full scale is 2 g)
Configurable minimum threshold. 1LSB = 16 mg @PEDO_4G=0, 1LSB = 32 mg
@PEDO_4G=1
Procedure to modify the pedometer minimum threshold:
 Write reg FUNC_CFG_ACCESS (01h) = 80h (Enables access to the embedded
functions registers)
 Set min threshold in bits [4:0] of reg 0Fh (1LSB = 16 mg @ FS = 2 g)
 Write reg FUNC_CFG_ACCESS (01h) = 00h (Disables access to the embedded
functions registers)
All modifications of the content of the embedded functions registers have to be performed
with the device in power-down mode.
