38.3.2 Data Ordering
The RGB color space format is required for viewing images on a display screen preview, and the YCbCr color space format is required for
encoding.
All the sensors do not output the YCbCr or RGB components in the same order. The ISI allows the user to program the same component
order as the sensor, reducing software treatments to restore the right format.

Mode Byte 0 Byte 1 Byte 2 Byte 3
Default Cb(i) Y(i) Cr(i) Y(i+1)
Mode1 Cr(i) Y(i) Cb(i) Y(i+1)
Mode2 Y(i) Cb(i) Y(i+1) Cr(i)
Mode3 Y(i) Cr(i) Y(i+1) Cb(i)
