Table 122. PEDO_DEB_REG_A register description
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 step counter
(debounce). Default value: 110
10.2
SM_THS_A (34h)

These bits define the threshold value which corresponds to the number of
steps to be performed by the user upon a change of location before the sig-
nificant motion interrupt is generated.
It is expressed as an 8-bit unsigned value. The default value of this field is
equal to 6 (= 00000110b).
