    The MAX22516 datasheet describe those registers:
    

    PAGE1_BYTE03 (0x1D): M-Sequency Capability
    This register contains information about implemented options related to M-sequences
    and physical configuration for the device.
    

    How to encode those options? Can I have a bit-per-bit description of that register?
    

    PAGE1_BYTE05 (0x1F): Process Data In (PDIn)
    This register contains the type and length of the Input Process Data (process data from
    the device to the IO-Link master).
    

    PAGE1_BYTE06 (0x20): Process Data Out (PDOut)
    

    This register contains the type and length of output data (process data from the IO-Link
    master to the device).
    

    How to encode type and lenght into this register?

      Hello,
      

      Thank you for your inquiry.  I would be happy to help.
      

      In general, the Direct Page 1 parameters are individual to your device. These registers are clearly defined in the IO-Link standard and you will need to refer to that to understand how to program these registers for your application. The Direct Page 1 Parameter registers in the MAX22516 should match the Page 1 parameters as listed and defined in the standard. 
      

      The latest revision of the IO-Link standard can be found here: IO-Link Interface and System Specification
      

      Please start with Table B.1 on page 248 and then look up the different Page 1 parameters that you are interested in. Each of these parameters is defined in much more detail throughout Appendix B.
      

      Thank you,
      

      Shasta

        Hello,
        

        Thanks for the quick reply. I was already researching the IO-Link standard when I heard your reply, but thanks for letting me know that appendix B, the encoding of these registers, is there.
        

        Thanks,
        

        Rogério
