Assembly Considerations
Insert sensor other electrical components into PCB. Insert into assembly clip bend leads degrees. Insert LED/clip assembly into PCB. Wave Solder entire assembly no-wash solder process utilizing solder fixture. solder fixture needed protect sensor during solder process. also sets correct sensor-to-PCB distance lead shoulders normally rest surface. fixture should designed expose sensor leads solder while shielding optical aperture from direct solder contact. Place lens onto base plate. Remove protective kapton tape from optical aperture sensor. Care must taken keep contaminants from entering aperture. Recommend place facing during entire mouse assembly process. Recommend hold first vertically kapton removal process. Insert assembly over lens onto base plate aligning post retain assembly. sensor aperture ring should self-align lens. optical position reference base plate lens. Note that motion button presses must minimized maintain optical alignment. Install mouse case. There MUST feature case press down onto clip ensure components interlocked correct vertical height.

Power management modes
ADNS-3040 three power-saving modes. Each mode different motion detection period, affecting response time mouse motion (Response Time). sensor automatically changes appropriate mode, depending time since last reported motion (Downshift Time). parameters each mode shown following table.
SCLK: Clock input. always generated master (the micro-controller). MOSI: Input data. (Master Out/Slave MISO: Output data. (Master In/Slave Out) NCS: Chip select input (active low). needs activate serial port; otherwise, MISO will high MOSI SCLK will ignored. also used reset serial port case error.
Motion Timing
motion level-sensitive output that signals micro-controller when motion occurred. motion lowered whenever motion set; other words, whenever there data Delta_X Delta_Y registers. Clearing motion reading Delta_Y Delta_X, writing Motion register) will motion high.
Chip Select Operation
serial port activated after goes low. raised during transaction, entire transaction aborted serial port will reset. This true transactions. After transaction aborted, normal address-to-data transaction-to-transaction delay still required before beginning next transaction. improve communication reliability, serial transactions should framed NCS. other words, port should remain enabled during periods non-use because EFT/B events could interpreted serial communication chip into unknown state. addition, must raised after each burst-mode transaction complete terminate burst-mode. port available further until burst-mode terminated.

SCLK, MOSI, driven directly micro-controller. port pins shared with other slave devices. When high, inputs ignored output tri-stated. lines that comprise port:

Required timing between Read Write Commands
There minimum timing requirements between read write commands serial port. rising edge SCLK last data second write command occurs before required delay (tSWW), then first write command complete correctly. rising edge SCLK last address read command occurs before required delay (tSWR), write command complete correctly. During read operation SCLK should delayed least tSRAD after last address data ensure that ADNS-3040 time prepare requested data. falling edge SCLK first address either read write command must least tSRR tSRW after last SCLK rising edge last data previous read operation.
Burst Mode Operation
Burst mode special serial port operation mode that used reduce serial transaction time motion read. speed improvement achieved continuous data clocking from multiple registers without need specify register address, requiring normal delay period between data bytes. Burst mode activated reading Motion_Burst register. ADNS-3040 will respond with contents Motion, Delta_Y, Delta_X, SQUAL, Shutter_Upper, Shutter_Lower Maximum_Pixel registers that order. burst transaction terminated after first bytes sequence read bringing high. After sending register address, micro-controller must wait tSRAD then begin reading data. data bits read with delay between bytes driving SCLK normal rate. data latched into output buffer after last address received. After burst transmission complete, micro-controller must raise line least tBEXIT terminate burst mode. serial port available until reset with NCS, even second burst transmission.
