After
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.

Step 1: Exit the Reset vector.
Step 2: Initialize TBLPAG and the Read Pointer (W6) for TBLRD instruction.
Step 3: Initialize the Write Pointer (W7) to point to the VISI register.
Step 4: Read and clock out the contents of the next two locations of executive memory through the VISI register
Step 5: Reset the device internal PC.
Step 6: Repeat Steps 4-5 until all 1024 instruction words of executive memory are read.

Reading the contents of executive memory can be
performed using the same technique described in
Section 3.8 “Reading Code Memory”. A procedure
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.
