About OP_FORMAT_SEL[7:0], IO, Address 0x03[7:0]
When the input video data is 8bit, even if this register setting is set to 10bit or 12bit output,
Does it work fine? (Do you want to mask the lower bits with no data with "0"?)

Best regards.
  • Hi,

    Please find the below comments,

      Does it work fine?

         Yes, I don't think it will create issues but in this case, the data will not be available on the respective pixel port pins which are mentioned on the section "Pixel Output Formats"(APPENDIX C) .



  • Hi.

    Sorry for the repetition, but what I wanted to confirm is the following.
    ・Is it possible to output without problems even if 8-bit video data is input with the following 10-bit output settings (2 x 20-bit mode 0)?
    OP_FORMAT_SEL[7:0] = 0x95
    ・When the above is output, are the lower bits with no data automatically masked to "0"?

    What does data not available mean?

    Do you mean no output?


  • Hi,

      As per expert comment, The output will follow the pixel output formats listed in appendix C.  Internally these device process the data as a 10-bit Stream, So It effectively converts the incoming 8-bits to 10-bits and uses that data.

    If we go from 8-bits to 10-bits the lower 2 bits is at best extrapolated data then we can't introduce accuracy into the original 8-bits. So its better to configure the OP_FORMAT_SEL register according to the input (Will have to do all our processing as based on the input only ).

     Please note that "  If your software really wants 10-bits then shift the 8 bits to the 10-bit MSB and set the low 10-bit LSB to 0.
