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
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.

Configuration
•
To configure this feature in an advanced register: See
Table 162: Advanced register: LUT
•
For information on GPDATA_BUFFER: See Chapter
Query limits from

Set EnableMemWR
to true (1)
Set AddrOffset to 0
Write
n databytes
in
GPDATA_BUFFER
Offset is increased
