The procedure for writing Configuration bits is similar to
the procedure for writing code memory, except that
16-bit data words are written (with the upper bytes read
being all ‘0’s) instead of 24-bit words. Since there are
multiple Configuration words or bytes, they are written
one word or byte at a time.
To change the values of the Configuration bits once
they have been programmed, the device must be Chip
Erased, as described in
gram
value. It is not possible to program a ‘0’ to ‘1’, but they
may be programmed from a ‘1’ to ‘0’ to enable code
protection.

Step 1: Exit the Reset vector.
Step 2: Set the NVMCON register to program one Configuration word.
Step 3: Initialize the TBLPAG register to the first page of program memory.
Step 4: Initialize the write pointer (W7) for the TBLWT instruction.
Step 5: Load the Configuration word data to W6.
Step 6: Write the Configuration word data to the write latch and increment the write pointer.
Step 7: Initiate the write cycle.

writing the Configuration bits.
In order to verify the data by reading the Configuration
bits after performing the write, the code protection bits
should initially be programmed to a ‘1’ to ensure that
the verification can be performed properly. After verifi-
cation is finished, the code protection bit can be pro-
grammed to a ‘0’ by using a word write to the
appropriate Configuration Word.
