Table 233. 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

Table 237. PEDO_DEB_REG register description
DEB_ TIME[4:0]
Debounce time. If the time between two consecutive steps is greater than
DEB_TIME*80ms, the debouncer is reactivated. Default value: 01101
DEB_ STEP[2:0]
Debounce threshold. Minimum number of steps to increment the step counter
(debounce). Default value: 110
