Description of the data path
Loading an LUT into the camera
Loading the LUT is carried out through the data exchange buffer called
GPDATA_BUFFER. As this buffer can hold a maximum of 2 kB, and a complete LUT
at 4096 x 10 bit is 5 kByte, programming cannot take place in a one block write
step because the size of an LUT is larger than GPDATA_BUFFER. Therefore, input
must be handled in several steps. The flow diagram below shows the sequence
required to load data into the camera.
