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.

One kind of data format is the boot protocol used in legacy environment as 5.2.1. The other kind of data format is USB report protocol format which includes Z-wheel movement data in the fourth byte as 5.2.2. The Z-wheel is moved forward the fourth byte data is 01H, the Z-wheel is moved backward the fourth byte data is FFH, and the Z-wheel is idle the fourth byte data is 00H. 5.2.1 USB Boot Protocol for Legacy Operation Byte 1 Bit 0 1 2 3~7 0-7 0-7 Description 1 = Left button pressed 1 = Right button pressed 1 = Middle button pressed Reserved X data (D0 - D7).

Application Circuit for PAW3504 6.2 PCB Layout Guideline The following guidelines apply to component placement and routing on the PCB. That will get an optimum EMC solution and tracking performance. 6.2.1 Key Components Placement Rules 1. Place resonator (Y1) near SENSOR pin1 and pin 14. 2. Place bulk capacitor (C2) and bypass (C5) near the USB CABLE. 3. Place C1 and C3 near SENSOR pin 6 and pin 7. 4. The C6/C7 and R4/R5 should be placed as close to the USB CABLE. 6.2.2 Routing Rules 1. Caps for pins 4, 6, 7 trace length must be less than 5 mm. 2. The trace length of OSCOUT, OSCIN must be less than 10 mm. 3.
