Table 263. 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 step counter
(debounce). Default value: 110
