By setting Reg0x20[1] = 1, the readout order of the columns will be reversed, as shown in
Figure 16. The starting color is preserved when mirroring the columns.
By setting Reg0x20[0] = 1, the readout order of the rows will be reversed as shown in
Figure 17. The starting color is preserved when mirroring the rows.
Reverse Readout
By setting Reg0x20[2] = 1 (Reg0x21 in context A), only half of the columns set will be read
out. An example is shown in Figure 18. Only columns with bit 1 equal to “0” will be read
out (xxxxxxx0x). The row skip works in the same way and will only read out rows with bit
1 equal to “0.” Row skip mode is enabled by setting Reg0x20[4]. For both row and col-
umn skips, the number of rows or columns read out will be half of what is set in Reg0x03
or Reg0x04, respectively.
The sensor can also be programmed to only read out a quarter of the specified window
size by setting Reg0x20[5:4], as shown in Figure 19. In all cases, the row and column
sequencing ensures that the Bayer pattern is preserved.
