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 16384 x 14 bit is 28 kByte, programming can not 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.
