CXD3615R
Detailed Description of Each Data
Shared data: D08 CTG [Category]
Of the data provided to the CXD3615R by the serial interface, the CXD3615R loads D09 and subsequent
data to each data register as shown in the table below according to D08 .

Description of operation
Loading to control data register
Loading to shutter data register
Note that the CXD3615R can apply these categories consecutively within the same vertical period. However,
care should be taken as the data is overwritten if the same category is applied.
Control data: D12 and D13 MODE [Drive mode]
The CXD3615R realizes various drive modes using control data D12 and D13 MODE, D16 NTPL and D17
CCD. The drive mode-related bits are loaded to the CXD3615R and reflected at the falling edge of VR. The
details are described below.
First, the various basic drive modes are shown below. These modes are switched using control data D12 and
D13 MODE.

These are both test mode for the ICX434.
Draft mode is the pulse elimination drive mode in the ICX432/434.
AF mode is the pulse eliminator drive mode based on draft mode, and is a high frame rate drive mode that can
be used for purposes such as auto focus (AF).
Frame mode is the ICX432/434 drive mode in which the data for all lines are read.
In addition to these modes, the CXD3615R has functions for switching the applicable CCD with D17 CCD,
and for switching VR/HR to NTSC equivalent or PAL equivalent with D16 NTPL.
Control data: D31 FLD [WEN/FLD output switching]
The WEN/FLD pin (Pin 5) output can be switched to the WEN pulse or the FLD pulse. The default is "WEN".
See the Timing Charts for the WEN pulse. The FLD pulse rises in the readout block in the A Field, and falls in
the horizontal period immediately thereafter. That is to say, FLD is a 1H high-active pulse. The transition points
are the same as for ID/WEN.
