    Work from the Type-C receptacle and follow the Type-C receptacle I/O definition

    • TX1/TX2 -> Output
    • RX1/RX2 -> Input

    HD3SS3220

    • SSTX input connects to HD3SS3220 TX1 and TX2
    • SSRX connects to HD3SS3220 RX1 and RX2

    Double check CPU TX and RX I/O definition

    TX -> Input or output?

    RX -> Input or output?

    Thanks

    David
