Programming model and register description

VS6724

102/118

0x2514

bOIFCLKRatio

Default value

0x1

Purpose

Determines the maximum PCLK output rate for the JPEG data, in

relation to the YUV pixel clock frequency

Type

BYTE

Possible values

0 ->PCLK is same frequency YUV pixel clock, for non JPEG

//for JPEG

1-> PCLK is 2 times slower

2-> PCLK is 4 times slower

3-> PCLK is 6 times slower

4-> PCLK is 8 times slower

5-> PCLK is 10 times slower

6-> PCLK is 12 times slower

7-> PCLK is 14 times slower

8-> PCLK is 16 times slower

9-> PCLK is 18 times slower

10-> PCLK is 20times slower

0x251b

0x251c

uwThres

Default value

0x0200

Purpose

Sets the number of bytes of JPEG data are present in each Packet

(line), must equal uwLinelength

Type

WORD

Possible values

The number of bytes in a line is 2 x the value programmed into this

Can be controlled in all stable states
