write to code memory. First, the device is configured for
writes, one instruction word is loaded into the write
latch, and the write point is incremented. Next, the write
sequence is initiated, and finally, the WR bit is checked
for the sequence to be complete. This process
continues for all words to be programmed.

Step 1: Exit the Reset vector.
Step 2: Set the NVMCON register to program one program memory word.
Step 3: Initialize the TBLPAG register to the first page of program memory.
Step 4: Initialize the write pointer (W2) for the TBLWT instruction.
Step 5: Load the lower instruction word to the W5 register and the upper instruction byte to the W6 register.
