Row Bin
The number of rows to be read and averaged per row output minus one. The rows will be read
independently into sampling capacitors, then averaged together before column readout. For
normal readout, this should be 0. For Bin 2X, it should be 1; for Bin 4X, it should be 3. Writes are
synchronized to frame boundaries. Affected by Synchronize_Changes. Causes a Bad Frame if
written. Legal values: [0, 3].
Reserved
Row Skip
The number of row-pairs to skip for every row-pair output. A value of zero means to read every
row. For Skip 2X, this should be 1; for Skip 3X, it should be 2, and so on. This value should be no less
than Row_Bin. For full binning, Row_Skip should equal Row_Bin.
Writes are synchronized to frame boundaries. Affected by Synchronize_Changes. Causes a Bad
Frame if written. Legal values: [0, 7].

Column Bin
The number of columns to be read and averaged per column output minus one. For normal
readout, this should be zero. For Bin 2X, it shoud be 1; for Bin 4X, it should be 3. Writes are
synchronized to frame boundaries. Affected by Synchronize_Changes. Causes a Bad Frame if
written. Legal values: {0, 1, 3}.
Reserved
Column Skip
The number of column-pairs to skip for every column-pair output. A value of zero means to read
every column in the active image. For Skip 2X, this should be 1; for Skip 3X, this should be 2, and so
on. This value should be no less than Column_Bin. For full binning, Column_Skip should equal
Column_Bin. Writes are synchronized to frame boundaries. Affected by Synchronize_Changes.
Causes a Bad Frame if written. Legal values: [0, 6].
