The
Color Tile Configuration Register; Table 12
, defines
the maximum number of lines and the maximum num-
ber of colors per line. A maximum of four row and four
column definitions are permitted. The
Color Tile Config-
uration Register
defaults to two lines and two colors per
line. The user should leave this register in default unless
a unique CFA option has been ordered.
This register can be configured to any pattern combina-
tion of 1, 2, or 4 rows and 1, 2, or 4 columns.
The Color Tile Row Definition registers;
Table 13
,
Table
14
,
Table 15
, and
Table 16
define the sequence of col-
ors for each respective line. Each byte wide line defini-
tion allows a maximum of four unique color definitions
using 2 bits per color in a given line. Gain programming
for each color was described earlier in this section. The
default line definitions are colors 00

for row 2 which supports a
Bayer pattern as defined in
section 2.2
. The user should
leave these registers in default unless a unique CFA op-
tion has been ordered.
For the default Bayer configuration of the color filter ar-
ray;

follows: Reg (01
