Problems using BF512 and S1D13506

Hi all,


    We are developing a product that need a camera and a TV out, so we may need two PPIs for the system, and for some reason we can't use bf561 or bf54x, so we choose bf512 and use an EPSON's s1d13506 chip for the tv output.


    We followed the EE-Note 184, and draw a schematic according to BF512 and S1D13506's datasheet, I put the schematic in the attachement.


    Now the problem is we can't write any data to the register memory of the S1D13506, does somebody know why or is there any mistakes in our design? Thanks!
