register.
The maximum value is 128. Since small changes in the current frame can result in changes in SQUAL, variations
in SQUAL are expected, when looking at a surface. Figure 29 shows 250 sequentially acquired SQUAL values,
while a sensor was moved slowly over white paper. SQUAL is nearly equal to zero when there is no surface below
the sensor.
