    Hi,

    From µChip MPLAB Programmers HELP :

    ID Location : Program or verify the User ID. You can set the User ID by selecting Configure>ID Memory.
    From '628 Datasheet

    14.10 User ID Locations
    Four memory locations (2000h-2003h) are designated
    as user ID locations where the user can store
    checksum or other code-identification numbers. These
    locations are not accessible during normal execution
    but are readable and writable during Program/Verify.
    Only the Least Significant 4 bits of the user ID locations
    are used for checksum calculations although each
    location has 14 bits.
    I'd recommend you to read The MPASM Help chapter relative to "__idlocs" ...

    I will become obvious for you, then ... even if you have a "non µChip" programmer.

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    deuhhh, yes there's an easier way.... Always nice to read MPASM PDF
    Wasn't it called " RTFM " in the good ol' Forum times ...

    Quand la censure ne coupait pas systématiquement tout ce qui pouvait ressembler à de l'humour ...

    Mheuuuuunoon, je l'ai pas dit ...
