Step 1: Exit Reset vector and erase the executive memory.
Step 2: Initialize pointers to read Diagnostic Words for storage in W6-W13.
Step 3: Repeat this step eight times to read Diagnostic Words, storing them in W registers, W6-W13.
Step 4: Initialize the NVMCON to erase the executive memory.
Step 5: Initiate the erase cycle.
Step 6: Repeat this step to poll the WR bit (bit 15 of NVMCON) until it is cleared by the hardware.
Step 7: Repeat Steps 5 and 6 to erase the rest of the executive memory. W1 should be incremented by 100h each
Step 8: Initialize the NVMCON to program 32 instruction words.
Step 9: Initialize TBLPAG and the Write Pointer (W2).
