    Scott:

    This is NOT true.  Interrupts do NOT need to be disabled around
    table reads.  As discussed at some length on the Microchip BBS, if
    this WERE true, interrupts would also have to be disabled around
    GOTOs and CALLs.

    MPSIM handles interrupts and PCL writes exactly as a 16C84 would.
