Programming Restrictions When Binning and Summing
Binning and summing require different sequencing of the pixel array and impose
different timing limits on the operation of the sensor.
As a result, when xy-subsampling is enabled, some of the programming limits declared
in the parameter limit registers are no longer valid. In addition, the default values for
some of the manufacturer-specific registers need to be reprogrammed. See “Minimum
Frame Time” and "Minimum Row Time" on page 43.
Subsampling / binning options:
1. XskipYskip
R0x3040[11], x_bin_en: 0
R0x3040[13], row_sum: 0
R0x0382: x_odd_inc = 3 (xskip2) or 7 (xskip4)
R0x0386: y_odd_inc = 3 (yskip2), 7 (yskip4) or 15 (yskip8)
2. XbinYskip
R0x3040[11], x_bin_en: 1
R0x3040[13], row_sum: 0
R0x0382: x_odd_inc = 3 (xbin2)
R0x0386: y_odd_inc = 3 (yskip2), 7 (yskip4) or 15 (yskip8)
3. XskipYsum
