Prod uces an end -of-line sequence that provid es basic calculations
includ ing "frame cou nter", "line sum", "pixels above threshold ",
"pixels below threshold ", and "d erivative line sum" w ithin the
region of interest. These basic calculations are used to calibrate
analog offset (cao) and calibrate analog gain (ccg).
To further aid in d ebugging and cable/ d ata path integrity, the
first three pixels after Line Valid are "aa", "55", "aa". Refer to the
follow ing table. These statistics refer only to pixels w ithin the
region of interest.

Description
By ensuring these values consistently
toggle betw een "aa" and "55", you can
verify cabling (i.e. no stuck bits)
Counter increments by 1. Use this value to
verify that every line is output
LSB justified . Use these values to help
calculate line average and gain
