3.5 Button and Z-Wheel Debounce Timing
Buttons and Z wheel of PAW3504DLY include detect and debounce function which are hardware implement.
When press button input signals need keeping low level up to 9.216ms. Button function just can catch data
otherwise debounce function will judge it is bounce issue. When scroll Z wheel input signals need keeping
turning level up to 0.896ms. Z wheel function just can catch data otherwise debounce function will judge it is
bounce issue. And the hardware sample rate is 2us so if bounce time is less than 2us the debounce function will
ignore it. Following the below specifications Buttons and Z wheel will work normally.
