Enabling the write protection of Configuration bits (WRTC = 0 in CONFIG6H) will prevent further writing of the
Configuration bits. Always write all the Configuration bits before enabling the write protection for Configuration bits.

Unlike code memory, the Configuration bits are
programmed a byte at a time. The Table Write, Begin
Programming 4-bit command (‘1111’) is used, but only
8 bits of the following 16-bit payload will be written. The
LSB of the payload will be written to even addresses and
the MSB will be written to odd addresses. The code
sequence to program two consecutive configuration
locations is shown in

The address must be explicitly written for
each byte programmed. The addresses
