Changing register values on the OV7670 using SCCB

Hello, I am trying to alter some register values to be able to use the PLL to multiply the input clock by 4 as you can see from the image the default value is 0x3A but i want to change it to 0x7A. Does anyone know a code for me to able to achieve this? I know that the SCCB is similar to I2C, but it doesnt seem that i am able to change the register values. I also forgot to mention that i am using the LPC1768 micro controller. Thank you in advance /media/uploads/sjaffal3/screenshot_2016-02-29_20.13.23.png

Are you writing your own code and library or working with an imported solution ?

Have you seen this project ? This post should answer your question.

I did look at that, and i tried the example but it just doesn't work, i should also mention that my camera is different as it doesn't have FIFO therefor i cant run the code and test it. I am trying to build my own library and took some examples from that code but it just doesn't work
