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.

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.
