    // - instance: This is the comportable IO instance name where the IO signal comes from.
    //
    // - connection: This key is similar to the connection key in the pinout/pad configuration and
    //               can have either of the following values:
    //
    //               1) 'direct': This is a dedicated IO signal that is directly connected to a pad.
    //                            Such an IO signal must also specify the 'port' and 'pad' keys
    //                            (see further below).
    //
    //               2) 'manual': This is a dedicated IO signal that is not directly connected to a pad.
    //                            It needs to be manually wired up in the template.
    //                            Such an IO signal may have a 'port' key, but no 'pad' key.

    // - port: Name of the available IO signal of the instance.
    //         This is required for 'direct' connections, but optional for the others.
    //         Individual signals of a bus IO signal must be indexed with square brackets, e.g. mybus[1].

    //
    // - pad: Name of the pad the 'direct' connection should connect to.
    //        This is not required for 'muxed' and 'manual' connections.
    //
    // - desc: Optional description field.
    //
    // - attr: Manual direct IOs may specify an additional pad attr field.
    //         This is used to create the correct pad attribute CSR for that DIO channel (since the
    //         DIO is manual, there is no way to automatically infer the corresponding pad type).
