Data Type: Upper 8 bits of a 9-bit unsigned integer.
USAGE: SQUAL (Surface Quality) is a measure of the number of valid features visible by the sensor in the cur-
rent frame. The maximum SQUAL register value is 128. Since small changes in the current frame can
result in changes in SQUAL, variations in SQUAL when looking at a surface are expected. The graph
below shows few sequentially acquired SQUAL values, while a sensor was moved slowly over white
paper. SQUAL is nearly equal to zero, if there is no surface below the sensor. SQUAL is typically maxi-
mized when the navigation surface is at the optimum distance from the imaging lens (the nominal
Z-height).

Data Type: Sixteen bit unsigned integer.
USAGE: Units are clock cycles. They must be read in this order: Read 0x06  rst, then 0x07. The shutter is con-
tinuously adjusted to keep the average and maximum pixel values within normal operating range.
The shutter value is automatically adjusted.
