Data Order
To read out the image data through the output channels,
the pixel array is organized in kernels. The kernel size is 64
pixels in x-direction by one pixel in y-direction.
The data order in 8-bit mode is identical to the 10-bit
mode. Figure 33 indicates how the kernels are organized.
The data order of this image data on the data output channels
depends on the subsampling mode.

• P1−SE/SN: Subsampling Disabled
♦ 32 LVDS Output Channels
The image data is read out in kernels of 64 pixels in
x-direction by one pixel in y-direction. One data channel
output delivers two pixel values of one kernel sequentially.
Figure 34 shows how a kernel is read out over the 32
output channels. For even positioned kernels, the kernels are
read out ascending, and for odd positioned kernels the data
order is reversed (descending).

♦ 16 LVDS Output Channels
Figure 35 shows how a kernel is read out over the 16
output channels. Each pair of adjacent channels is
multiplexed into one channel. For even positioned kernels,
the kernels are read out ascending but in pair of even and odd
pixels, while for odd positioned kernles the data order is
reversed (descending) but in pair of even and odd pixels.
