    PROGRAMMING VERIFICATION
    After
    the
    programming
    executive
    has
    been
    programmed to executive memory using ICSP, it must
    be verified. Verification is performed by reading out the
    contents of executive memory and comparing it with
    the image of the programming executive stored in the
    programmer.
    Reading the contents of executive memory can be
    performed using the same technique described in
    for reading executive memory is shown in Table 5-6.
    Note that in Step 2, the TBLPAG register is set to 80h,
    such that executive memory may be read. The last
    eight words of executive memory should be verified
    with stored values of the Diagnostic and Calibration
    Words to ensure accuracy.

    Step 4: Read and clock out the contents of the next two locations of executive memory through the VISI register
    using the REGOUT command.
