Power management modes
The ADNS-6030 has three power-saving modes. Each
mode has a different motion detection period, affecting
response time to mouse motion (Response Time). The
sensor automatically changes to the appropriate mode,
depending on the time since the last reported motion
(Downshift Time). The parameters of each mode are
shown in the following table.
Motion Pin Timing
The motion pin is a level-sensitive output that signals the
micro-controller when motion has occurred. The motion
pin is lowered whenever the motion bit is set; in other
words, whenever there is data in the Delta_X or Delta_Y
registers. Clearing the motion bit (by reading Delta_X
and Delta_Y, or writing to the Motion register) will put the
motion pin high.
LASER Mode
For power savings, the VCSEL will not be continuously on.
ADNS-6030 will flash the VCSEL only when needed.

Synchronous Serial Port
The synchronous serial port is used to set and read
parameters in the ADNS-6030, and to read out the motion
information.
The port is a four-wire port. The host micro-controller
always initiates communication; the ADNS-6030 never
initiates data transfers. SCLK, MOSI, and NCS may be
driven directly by a micro-controller. The port pins may
be shared with other SPI slave devices. When the NCS
pin is high, the inputs are ignored and the output is tri-
stated.
The lines that comprise the SPI port:
SCLK:
MOSI:
MISO:
NCS:
Chip Select Operation
The serial port is activated after NCS goes low. If NCS
is raised during a transaction, the entire transaction is
aborted and the serial port will be reset. This is true for
all transactions. After a transaction is aborted, the normal
address-to-data or transaction-to-transaction delay is
still required before beginning the next transaction. To
improve communication reliability, all serial transactions
should be framed by NCS. In other words, the port
should not remain enabled during periods of non-use
because ESD and EFT/B events could be interpreted as
serial communication and put the chip into an unknown
state. In addition, NCS must be raised after each burst-
mode transaction is complete to terminate burst-mode.
The port is not available for further use until burst-mode
is terminated.

low to activate the serial port; otherwise, MISO
will be high Z, and MOSI & SCLK will be ignored.
NCS can also be used to reset the serial port in
case of an error.
