    Thread Summary
    
                The user asked how to parse the BOOT_REV 16-bit value for the ADIS16497. The support engineer clarified that it is a two-digit BCD, where 0x0331 represents revision 3.49. This value is intended for warranty support and not correlated with other public-facing information.

    How do I parse the  BOOT_REV correctly.
    

    Is 16-bit value 0x0303 = revision 3.3
    

    Is 16-bit value 0x0331 = revision 3.31
    

    Is 16-bit value 0x03FF = revision 3.255
    

    The datasheet doesn't specify how to parse the value.
    

    I'm presenting this value in a GUI, so that is why I want to know this.

      Thank you for your use of the ADIS16497 and for posting your question in this forum.  
      

      The reason that this was not provided in the product datasheet, is this is not correlated with any other public-facing information. The intended use was for warranty support, in the event of returns or failure analysis.  
      

      Having said that, the (internal) design documentation, which I have easy access to, appears to define this a two-digit, binary coded digital (BCD).  
      

      Assuming a 2-digit BCD, 0x0331 would represent 3.49 (31h = 49d).
      

      I hope that this helps.
