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 kByte, and a com-
plete LUT at 4026 x 8 bit is 4 kByte, programming can’t 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.

•
To configure this feature in an advanced register: See
Table 89: Advanced register: LUT
•
For information on GPDATA_BUFFER: See Chapter
Query limits from

GPDATA_INFO
Set EnableMemWR
to true (1)
Set AddrOffset to 0
Write n databytes
in
GPDATA_BUFFER
Offset is increased
in camera after n
bytes are written
Check
