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 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.
