PEDO_THS_REG (0Fh)

Table 152. PEDO_THS_REG register default values

Table 153. PEDO_THS_REG register description

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)

Note:

All modifications of the content of the embedded functions registers have to be performed

with the device in power-down mode.

PEDO_ 4G

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)

THS_ MIN[4:0]

Configurable minimum threshold. 1LSB = 16 mg @PEDO_4G=0, 1LSB = 32 mg

@PEDO_4G=1

SM_THS[7:0]

Significant motion threshold. Default value: 00000110
