Multiple values cannot be specified in a single
command; to embed multiple items, issue
separate commands for each one. Information
items are presented in the order in which they
appear in the last pixels of the last line in an
image. If images are offset by ROIs, the location
of chunk data is adjusted to fit within the last ROI.
chnksel none
icsum value
value is 0 (disabled) or 1 (enabled)
When icsum=1, a checksum is embedded in the
last bytes of the last line of an image. A total of 8
bytes are used. The first 7 bytes are programmed
0 (black). The last bytes is the checksum value. In
2-tap mode, the checksum is a 10-bit value. All
remaining bits are padded with 0's.
