bitec hsmc quad video - chrontel missing register

Honored Contributor II

Hi all 

Did anybody work on the bitec cyclone iii ep3c120f780 development base kit (http://www.altera.com/products/devkits/altera/kit-cyc3.html)? 

I am trying to configure the chrontel dvi converter to output a test pattern generator, but it does not seems to work at all. 

I am using the usual settng fot the VGA (1024x768) wich I use onto the other dvi devices, and I know that they work, but on this converter they does not seem to be correct. 

furtherore, looking at the quad video mosaic(http://www.bitec.ltd.uk/ciii_video_dev_kit.html) and wathcing I2c software configurations that the use, i notice that the header i2c.c configures a register (0x15) that i am not able to find on the chrontel datasheet. 

Could anyone help me about this matter?
