USB_RESET USB Spec: Notes: D+/D- low for an extended period A device may reset after seeing an SE0 for more than 18.7 uS, and defi nitely after 10 mS. After power up and prior to Reset, the device will not respond to any USB commands. After the device has been given a USB Reset, the device’s address will be reset to zero and the device will be in the Default state. The chip will default to Report protocol and any pending output will be fl ushed. All registers will be reset to a state that matches power-on-reset with the following exceptions: USB State register will be “Default” instead of “Attached” . USB_SUSPEND USB Spec: Notes: Idle state for an extended period A device may suspend after seeing an idle for more than 3 mS, and defi nitely after 10 mS. The chip will take a minimum of 5 mS to start Suspend, though will defi nitely start after 6 mS. The chip may fi nish the current frame if necessary before stopping the clock. Thus, an additional frame time may be used to reach Suspend mode. USB_RESUME USB Spec: Notes: Non-idle state Remote Resume signalling from a device must be between 1 mS and 15 mS. The host is required to send Resume signaling for 20 mS plus 10 mS of resume recovery time in which it does not access any devices. This allows devices enough time to wake back up. The chip can cause a Resume if Remote Wakeup is enabled and a button has been pressed. Remote resume signalling from the chip will last 11.45 mS to 12.45 mS.

Clear_Feature_Device Default: Addressed: Confi gured: Notes: 00 01 01 00 00 00 00 00 Accept (undefi ned in USB Spec) Accept Accept This clears the remote wakeup bit.

Clear_Feature_Endpt1 Default: Addressed: Confi gured: Notes: 02 01 00 00 81 00 00 00 Stall (undefi ned in USB Spec) Stall Accept See Set_Feature_Endpt1. Set_Idle Default: Addressed: Confi gured: Notes: 21 0A 00 rr 00 00 00 00 rr = rate in multiples of 4 mS Accept Accept Accept The third byte of the command is to select the Report ID. There is only one for the mouse – so, using either 00 or 01 will work. The fourth byte of the command sets the rate in multiples of 4 mS. The initial value for mice will be x00 which means “infi nite” – that is packets only come out when there is a change in data. Data will only be allowed to come out when the device is confi gured. However, the chip will accept the command in Default or Addressed mode and use that value when the device is later confi gured. Set_Vendor_Test Default: Addressed: Confi gured: Notes: 40 01 00 00 xx yy 00 00 xx = address yy = data Accept Accept Accept Address range for “xx” should be 0x00 to 0x3F. Addresses above this are reserved for possible future use. See also Get_Vendor_Test. PixArt Imaging Inc.

Poll_Endpt1 Returns: Default: Addressed: Confi gured: Notes: bb xx yx yy zz bb = button byte xx = X motion byte yx = XY motion byte yy = Y motion byte zz = Z motion byte (if Z-Wheel) Ignore request Ignore request Accept (NAK if no data; Send packet if available) See also Get_HID_Input. Endpt will only stall if halt bit is set by Set_Feature_Endpt1. Details of data packet are below. Endpt1 should be polled at least every 10 frames (mS). It is typically polled every 8 frames on Windows machines. For internal testing, Endpt1 can be continuously polled if desired. The chip will not generate any report packets unless in the Confi gured state. If Endpt1 is currently empty, any motion or button change will be loaded into the Endpt1 buff ers. Once the Endpt1 buff ers are full, any further motion events will get accumulated. When the Endpt1 buff ers are later polled and emptied, the current accumulated X/Y/Z values will be loaded into the Endpt1 buff ers. After transferring their data, the accumulation registers are reset so they are ready to start ac- cumulating new motion events. Button information is handled a bit diff erently. If the Endpt1 buff ers are empty, and a button change event occurs, the new button state is put into the Endpt1 buff ers. At the same time, the button state that is put in Endpt1 is copied for later use. While Endpt1 is full, changes in button state are essentially ignored. When Endpt1 is emptied, if the current button state is diff erent than that which was last loaded into Endpt1, then the new state will be loaded and a new copy saved. Basically, the button state that is loaded into Endpt1 is always the current button state at that point in time. It should also be noted that there is hardware on the chip to help de-bounce the buttons. Special note on wLength: The wLength paramater in commands specifi es the maximum number of bytes a device should send back. The commands listed below are not able to handle a wLength of 0 correctly. Get_Status_Device Get_Status_Interface Get_Status_Endpt0 Get_Status_Endpt1 Get_Confi guration Get_Interface This chip will send one byte of data rather than none when wLength = 0 is requested for the above commands.

The sensor can be programmed through registers, via the USB port, and confi guration and motion data can be read from these registers. The registers will be “disabled” by VDDA5 going low or sending a USB reset command.
