Valid data bits: 11
The code_1 setup register is used to select different basic operating modes:
Note:
Decreasing the system clock rate proportionately increases sensor sensitivity (by increasing
exposure time), but also decreases frame frequency. System Clock must be x1 for standard
CCIR or EIA framing.

Selects between normal and backlit exposure
modes. The power-on default is normal mode. See
Exposure Control for full description
Selects between a linear (LIN=1) or gamma cor-
gamma corrected.
Allows automatic gain control to be inhibited. The
current gain value selected is frozen. With AGC=0 a
new gain value can be written to the gain register via
the serial interface (header code 0101).
Allows automatic black calibration to be inhibited.
Allows automatic exposure control to be inhibited.
The current exposure value selected is frozen. Note
that if automatic exposure control is inhibited then
automatic gain control is also disabled. With AEC=0
a new exposure value can be selected by writing to
the coarse and fine exposure registers via the serial
interface (header codes 0011 & 0100).
Shuffles the read out of the horizontal shift register.
Even columns read out together then odd columns.
Shuffles the readout of the vertical shift register.
Even lines read out together then odd lines.
Requests a re-calibration of the black level while bit
is low.
System clock division: (see Note)
0,0=1; 0,1=÷2; 1,0=÷4; 1,1=÷8
