Burst Mode Operation
Burst mode is a special serial port operation mode which
may be used to reduce the serial transaction time for
three predefined operations: motion read and SROM
download and frame capture. The speed improvement is
achieved by continuous data clocking to or from multiple
registers without the need to specify the register address,
and by not requiring the normal delay period between
data bytes.

Motion Read
This mode is activated by reading the Motion_Burst
register. The ADNS-3060 will respond with the contents
of the Motion, Delta_X, Delta_Y, SQUAL, Shutter_Upper,
Shutter_Lower and Maximum_Pixel registers in that
order. After sending the register address, the micro-
controller must wait t
data. All 56 data bits can be read with no delay between
bytes by driving SCLK at the normal rate. The data are
latched into the output buffer after the last address bit
is received. After the burst transmission is complete, the
micro-controller must raise the NCS line for at least t
to terminate burst mode. The serial port is not available
for use until it is reset with NCS, even for a second burst
transmission.
