2 byte CRC-16 of previous bytes
e.g. PC-30-02k80 would have
2048 words of red +
2048 words of green +
2048 words of blue +
32 unused bytes +
2 byte CRC of the above
2 byte PRNU is an unsigned integer from 0 to 61,438
This value will be converted to the PRNU coefficient as
follows:
PRNU = 1 + value / 4096
Therefore the PRNU range is 1 to 15.9995 and the formula to
calculate the value is:
value = 4096 x (PRNU -1)
See WFC for a description of the CRC algorithm

PRNU coefficients are only loaded from non-volatile memory
on: power-up, LPC, and LFS. They are not loaded by LUS.

End-of-line Sequence
Purpose: Produces an end-of-line sequence that provides basic
calculations including "line counter", "line sum", "pixels above
threshold", "pixels below threshold", and "derivative line sum"
within the region of interest.
To further aid in debugging and cable/data path integrity, the
first three pixels after Line Valid are AA
16
, 55

, AA

. Refer to
the following table. These statistics refer only to pixels within
the region of interest.
