RGB555 data is output to memory with data expansion. Figure 6-40 shows the storage format for RGB555
data.

6.2.4.5.3.3 Camera ISP CSI2 RAW Bayer RGB Operating Modes
6.2.4.5.3.3.1 Camera ISP CSI2 RAW6
RAW6 data can be output only with data expansion. The line length sent through the CSI2 physical layer
is a multiple of 8 bits. Furthermore, the line length is a multiple of 3x8 bits to correctly complete the pixel
reconstruction (the lowest common multiple of 8 and 6 is 24, so 3x8 bits).
Figure 6-41 shows the storage
format for RAW6 data.
