Notes on Shutdown and Forced Rest
The ADNS-3550 can be set in Rest mode through the
Configuration_Bits register (0x11). This is to allow for
further power savings in applications where the sensor
does not need to operate all the time.
The ADNS-3550 can be set in Shutdown mode by
asserting the SHTDWN pin. For proper operation,
SHTDWN pulse width must be at least tSHTDWN. Shorter
pulse widths may cause the chip to enter an undefined
state. In addition, the SPI port should not be accessed
when SHTDWN is asserted. (Other ICs on the same SPI
bus can be accessed, as long as the sensor’s NCS pin is
not asserted.) The table below shows the state of various
pins during shutdown. After deasserting SHTDWN, a full
reset must be initiated. Wait tWAKEUP before accessing
the SPI port, then write 0x5A to the POWER_UP_RESET
register. Any register settings must then be reloaded.

*NCS pin must be held to 1 (high) if SPI bus is shared with other
devices. It can be in either state if the sensor is the only device in
addition to the microcontroller.
Note: There are long wakeup times from shutdown and forced Rest.
These features should not be used for power management during
normal mouse motion.
Registers
The ADNS-3550 registers are accessible via the serial
port. The registers are used to read motion data and
status as well as to set the device configuration.
