CIS Line-By-Line Rotating Gain and Offset
(Configuration DB1 = 1, DB0 = 1)
Line-by-line rotating gain and offset minimizes the
amount of write cycles per scan. Pre-loaded values of
gain and offset can be loaded for each color before the
first line is scanned. Each gain and offset is cycled
through line-by-line so that the gain and offset do not
have to be loaded in between lines. Below is the typical
application circuit and timing for this configuration.
