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 17. 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. You can configure the number of windows used in the application (one to four). Figure 18 shows how to configure two
windows spread over the image array.
