CMOS Optical Mouse Sensor
3. Registers and Operation
The mouse sensor can be programmed through registers, via the serial port, and DSP configuration and motion
data can be read from these registers. All registers not listed are reserved, and should never be written by mouse
controller.

Motion
Reserved[2:1]

RES[1:0]
Register 0x16 allows the user to determine if motion has occurred since the last time it was read. If
so, then the user should read registers 0x17 and 0x18 to get the accumulated motion. It also tells if the
motion buffers have overflowed since the last reading. The current resolution is also shown.
Reading this register freezes the Delta_X and Delta_Y register values. Read this register before
reading the Delta_X and Delta_Y registers. If Delta_X and Delta_Y are not read before the motion
register is read a second time, the data in Delta_X and Delta_Y will be lost.
