    RPM = ((1024 - ( ADRESH:ADRESL))* RPMmax) /1024

    depending on the processor used, you'll need to use or PBPL(ongs) or DIV32 ...

    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 " !!!

    as 1024 and RPMmax are both constants, do that math at compile time.
