Bit field
The value in this register reflects the last USB delta Y data output or data queued for
output.
Register 0x03 should be read before register 0x04 (Delta Y), else Delta Y will return 0.
This register is included for test purposes only. For navigation use, use the HID defined
commands. Data is 8 bit, 2’s complement. Absolute value is determined by the currently
set resolution.

Eight bit number.
SQUAL is a measure of the number of features visible by the sensor in the current
frame. The maximum value is 144. Since small changes in the current frame can result in
changes in SQUAL, slight variations in SQUAL on one surface is expected.

Eight bit number.
The combination of Shutter_Upper and Shutter_Lower is a 16-bit number. This is the
number of clocks the shutter was open for the last image taken. The units are in main
clocks ticks (nominally 24MHz). To avoid split read issues, read Shutter_Upper first.
