Data Type:
Sixteen bit unsigned integer
USAGE:
Units are clock cycles. Read Shutter_Upper first, then Shutter_Lower. They should be read consecu-
tively. The shutter is adjusted to keep the average and maximum pixel values within normal operating
ranges. The shutter value is automatically adjusted.

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 current
frame. The maximum SQUAL register value is 167. Since small changes in the current frame can result
in changes in SQUAL, variations in SQUAL when looking at a surface are expected.
