Reverse Scan
Reverse scanning is supported in the X and Y direction. Line 0 (first line on the output) is the top line in normal mode and the bottom
line in reverse scanning, as shown in
Figure
25. As a result, the line numbers always increment. When reverse scanning in X, the
operation is analogous. To enable reverse readout in X and Y, set the seqmode4[6:7] bits. In addition, the Y_start and X_start
addresses must be changed to the new starting address.

Multiple Windows
The sequencer supports the readout of four different windows, randomly positioned over the pixel array. The images are read out
sequentially. That is, window 1 is read out before window 2, even if both windows show some overlap. Next, windows 3 and 4 are
read out. Each window is treated as a frame and images are read out as shown in
Figure
27. Also, the sum of readout times of all
four windows should be less than or equal to the sum of reset time and integration time. (RTw1+RTw2+RTw3+RTw4) < (Reset time
+ Integration time). You can configure the number of windows used in the application (one to four).
Figure 26
shows how to configure
two windows spread over the image array.
