Function Description
In the 24-bit mode, color difference output (CB: B-Y). And in the
16-bit mode, CBOUT0 gives the Cr flag: "H" level for Cr output.
In the 24-bit mode, color difference output (CR: R-Y). And in the
16-bit mode, these pins yield multiplexed Cr/Cb output.
Luminance signal output (Y)
Test pins Keep these pins at "L" level.
