Step 1: Exit the Reset vector.
Step 2: Initialize the Write Pointer (W7) for the TBLWT instruction.
Step 3: Set the NVMCON register to program CW4.
Step 4: Initialize the TBLPAG register.
Step 5: Load the Configuration register data to W6.
Step 6: Write the Configuration register data to the write latch and increment the Write Pointer.
Step 7: Initiate the write cycle.
Step 8: Repeat this step to poll the WR bit (bit 15 of NVMCON) until it is cleared by the hardware.
Step 9: Reset device internal PC.
Step 10: Repeat Steps 5-9 to write CW3 to CW1.
