Block diagram The PAN3101 is a low cost CMOS-process optical mouse sensor with DSP integration chip that serves as a non-mechanical motion estimation engine for implementing a computer mouse. It is based on new optical navigation technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. The sensor is in a 8pin optical package. The current X and Y information are available in registers accessed via a serial port.

Serial Interface The synchronous serial port is used to set and read parameters in the PAN3101, and can be used to read out the motion information instead of the quadrature data pins. SCLK: The serial clock line. It is always generated by the host micro-controller. SDIO: The serial data line used for write and read data. 5.1 Transmission Protocol The transmission protocol is a two-wire link, half duplex protocol between the micro-controller and PAN3101. All data changes on SDIO are initiated by the falling edge on SCLK. The host microcontroller always initiates communication; the PAN3101 never initiates data transfers. The transmission protocol consists of the two operation modes: - Write Operation. - Read Operation. Both of the two operation modes consist of two bytes. The first byte contains the address (seven bits) and has a bit7 as its MSB to indicate data direction. The second byte contains the data. SECOND BYTE FIRST BYTE R /W (1 BIT) ADDRESS (7 BIT) MSB DATA (8 BIT) LSB LSB MSB Figure 6. Transmission protocol 5.1.1 Write Operation A write operation, which means that data is going from the micro-controller to the PAN3101, is always initiated by the micro-controller and consists of two bytes. The first byte contains the address (seven bits) and has a “1” as its MSB to indicate data direction. The second byte contains the data. The transfer is synchronized by SCLK. The micro-controller changes SDIO on falling edges of SCLK. The PAN3101 reads SDIO on rising edges of SCLK.

Write operation 5.1.2 Read Operation A read operation, which means that data is going from the PAN3101 to the micro-controller, is always initiated by the micro-controller and consists of two bytes. The first byte contains the address, is written by the micro-controller, and has a “0” as its MSB to indicate data direction. The second byte contains the data and is driven by the PAN3101. The transfer is synchronized by SCLK. SDIO is changed on falling edges of SCLK and read on every rising edge of SCLK. The micro-controller must go to a high Z state after the last address data bit. The PAN3101 will go to the high Z state after the last data bit.

Read operation 5.2 Re-Synchronous Serial Interface 5.2.1 Power On Problem The problem occurs if the PAN3101 powers up before the microprocessor sets the SCLK and SDIO lines to be output. 5.2.2 ESD Events The PAN3101 and the micro-controller might get out of synchronization due to ESD events. If the PAN3101 and the micro-controller might get out of synchronization due to power on problem or ESD events. An easy way to solve this is to waiting for watchdog timer timeout 5.3 Collision Detection on SDIO The only time that the PAN3101 drives the SDIO line is during a READ operation. To avoid data collisions, the micro-controller should release SDIO before the falling edge of SCLK after the last address bit. The PAN3101 begins to drive SDIO after the next falling edge of SCLK. The PAN3101 release SDIO of the rising SCLK edge after the last data bit. The micro-controller can begin driving SDIO any time after that. In order to maintain low power consumption in normal operation, the micro-controller should not leave SDIO floating until the next transmission (although that will not cause any communication difficulties). 5.4 Serial Interface Watchdog Timer Timeout When there are only two pins to read register from PAN3101, and PD pin can’t be used to re-synchronous function. If the microprocessor and the PAN3101 get out of sync, then the data either written or read from the registers will be incorrect. In such a case, an easy way to solve this condition is to toggle the SCLK All rights strictly reserved any portion in this paper shall not be reproduced, copied or transformed to any other forms without permission. 16 PixArt Imaging Inc.

After setting the configuration register, wait at least 1frame times. To get the chip out of the power-down mode, clear bit 6 in the configuration register via a serial port write operation. In power-down mode, the serial interface watchdog timer is not available. But, The serial interface still can read/write normally. For an accurate report after leave power down mode, wait about 3ms before the micro-controller is able to issue any write/read operation to the PAN3101.
