3.6 Button and Z-Wheel Debounce Timing
Buttons and Z wheel of PAW3529DH-TXWA include detect and debounce function which are hardware
implemented. 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.
