Read Mode 2 (RW)
Mirror Row
When set, row readout in the active image occurs in reverse numerical order starting from (Row_Start +
Row_Size). When clear, row readout of the active image occurs in numerical order. This has no effect on
the readout of the dark rows. Writes are synchronized to frame boundaries. Affected by
Synchronize_Changes. Causes a Bad Frame if written.
Mirror Column
When set, column readout in the active image occurs in reverse numerical order, starting from
(Column_Start + Column_Size). When clear, column readout of the active image occurs in numerical
order. This has no effect on the readout of the dark columns. Writes are synchronized to frame
boundaries. Affected by Synchronize_Changes.
Reserved
Show Dark Columns
When set, the dark columns will be output to the left of the active image, making the output image
wider. This has no effect on integration time or frame rate. When clear, only columns that are part of
the active image will be output. Writes are synchronized to frame boundaries. Affected by
Synchronize_Changes.
Show Dark Rows
When set, the dark rows will be output before the active image rows, making the output image taller.
This has no effect on integration time or frame rate. When clear, only rows from the active image will
be output. Writes are synchronized to frame boundaries. Affected by Synchronize_Changes.
Reserved
Row BLC
When set, digitally compensate for differing black levels between rows by adding Dark Target (R73) and
subtracting the average value of the 8 same-color dark pixels at the beginning of the row. When clear,
digitally add Row Black Default Offset (R75) to the value of each pixel.
Column Sum
When set, column summing will be enabled, and in column bin modes, all sampled capacitors will be
enabled for column readout, resulting in an effective gain equal to the column bin factor. When clear,
column averaging will be done, and there will be no additional gain related to the column bin factor.
Writes are synchronized to frame boundaries. Affected by Synchronize_Changes.

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].
