Output data formats

The VS6624 supports the following data formats:

●

YUV4:2:2

●

YUV4:0:0

●

RGB565

●

RGB444 (encapsulated as 565)

●

RGB444 (zero padded)

●

Bayer 10-bit

●

Bayer 8-bit

The required data format is selected using the bdataFomat control found in the pipe setup

bank registers. The various options available for each format are controlled using the

bRgbsetup and bYuvSetup registers found in the

Output formatter control registers.

Line / Frame Blanking Data

The values which are output during line and frame blanking are an alternating pattern of

0x10 and 0x80 by default. These values may be changed by writing to the BlankData_MSB

and BlankData_LSB registers in the

Output formatter control bank.

YUV 4:2:2 data format

YUV 422 data format requires 4 bytes of data to represent 2 adjacent pixels. ITU601-656

defines the order of the Y, Cb and Cr components as shown in

Figure 6.

Standard Y Cb Cr data order

The VS6624 bYuvSetup register can be programmed to change the order of the

components as follows:
