As specified in the above data output timing diagram, the timing margin between video clock pin
(VCLK) and data pins (Y[7:0] or C[7:0]) is about 4ns ~ 5ns. This margin may be sufficient or not
according to how much video clock and data pins are delayed internally in the backend chip,
respectively. To safely latch the data output in the backend chip, it is recommended that data be
latched at negative edge of VCLK. The above timing margin diagram represents 16bit output interface,
but is also valid for 8bit output interface.
Output Data Format
Output Format is controlled by configuring Output Format register[31h]. Configurable options are
specified again for your reference.

Cb First
Cb pixel in front of Cr pixel in 16bit or 8bit video data output modes
Y First
Y pixel in front of Cb and Cr pixels in 8bit video output mode. This option is
meaningful only with 8bit output mode.
8 Bit Output
Image Data is produced only in Y[7:0]. C[7:0] should be discarded
