    Hi Amildm,

    Good day.

    Thank you for your patience.

    Regarding to your question, you can wrap it based on your equipment, and Intel can only provide the aux-data format.

    The aux-data width is not changable but you can wrap it to another format.

    Customer can re-organize it to another format which means re-organize the structure/positioning of data.

    HDMI Intel® FPGA IP User Guide

    Intel provide the aux_data interface to show HB0~HB2, PB0~PB27....

    There are only 4 phases for aux_data interface. on the 1st phase, aux_data[71:0] presents {PB22,PB21,PB15,PB14,PB8,PB7,PB1,PB0,HB0} and so on

    You may re-organize it based on the same phase/block.

    You can store all HB/PB registers in 4 phases into 72 registers. then re-organize them to another structure.

    Hope this answers your question.

    Thank you.

    Best Regards,
