RAW8 data format can be output to memory in two formats: with no data expansion and with data
expansion.
The line length sent through the associated PHY is a multiple of 32 bits.
Figure 6-16 shows RAW8 format.
NOTE:
• Use RAW8 data format to output RAW6 and RAW7 data formats to memory.
• Use VP to output RAW8 data to the video port: VP is equivalent to
RAW8 + VP.
