Step 1: Exit the Reset vector.
Step 2: Set the NVMCON to program 64 instruction words.
Step 3: Initialize the write pointer (W7) for TBLWT instruction.
Step 4: Initialize the read pointer (W6) and load W0:W5 with the next 4 instruction words to program.
Step 5: Set the read pointer (W6) and load the (next set of) write latches.
Step 6: Repeat steps 4-5 sixteen times to load the write latches for 64 instructions.
Step 7: Initiate the write cycle.
Step 8: Wait for Row Program operation to complete and make sure WR bit is clear.
