8-bit Format (HREF total 292)
– 1st HREF Y channel output unstable data.
– 2nd HREF Y channel output B11 G21 R22 G12 ...
– 3rd HREF Y channel output B31 G21 R22 G32 ..., etc.
– PCLK timing is double and PCLK rising edge latch data bus. UV channel tri-state. Every line data output twice.
4-bit Nibble Mode Output Format
– Uses higher 4 bits of Y port (Y[7:4]) as output port.
– Supports YCrCb/RGB data, CCIR601/CCIR656 timing, Color/B&W.
– Output sequence: High order 4 bits followed by lower order 4 bits
Y0h Y0l Y1h Y1l ...
U0h U0l V0h V0l ...
For B/W or one-line RGB raw data, the output data clock speed is doubled. For color YUV, output clock is four times that of the 16-bit output
data. In color mode, sensor must be set to 8-bit mode, and the nibble timing, clock divided by 2.
– Output sequence: U0h U0l Y0h Y0l V0h V0l Y1h Y1l ...
