ply droops or micro-controller firmware flaws. In such
a case, the micro-controller should pulse NCS high for
at least 1 ms. The ADNS-3060 will reset the serial port

may sometimes be required (for example, due to a
USB suspend interrupt during a read operation). To
accomplish this the micro-controller should raise NCS.
The ADNS-3060 will not write to any register and will
reset the serial port (but not the control registers) and
be prepared for the beginning of future transmissions
