Description
KA3312 is a high performance and ultra low power CMOS-processed optical image sensor with integrated digital image process circuits. It is based on an optical navigation technology which measures changes in position by optically acquiring sequential surface images(frames) and mathematically determining the speed, the direction and the magnitude of motion. The displacement delta_X and delta_Y information are available in registers which are accessible through SPI serial interface. A host controller reads and translates the data from the SPI serial interface into RF signals before sending them to the host PC. The word "sensor", instead of KA8G2, is used in the document.

Specification:

Serial Interface
3-wired SPI Serial Interface
The sensor supports 3-wired Serial Peripheral Interface (SPI). The host controller can use the SPI to write and read registers in the sensor,and to read out the motion information. The host controller always initiates communication; the sensor never initiates data transfers. NCS,SCLK and SDIO may be driven directly by the host controller. SDIO may also be driven by the sensor when data is read out from sensor registers.
• NCS : Chip select input (active low). NCS needs to be low to activate the SPI; otherwise, SDIO will be at high-Z state and SCLK will be ignored. NCS can also be used to reset the SPI in case an communicational error happens.
• SCLK : Clock input. It is always generated by the host controller.
• SDIO : Bi-directional input/output data
Transmission Protocol
The transmission protocol is a 3-wired link, half duplex protocol between the host controller and the sensor. All data changes on SDIO are initiated by the falling edge on SCLK. The host controller always initiates communication; the sensor never initiates data transfers. The transmission protocol consists of the following two operation modes.
