3.5
The code sequence detailed in Table 3-5 should be
used, except that the address used in “Step 2” will be in
the range of 000000h to 0007FFh, 000000h to
000FFFh or 000000h to 001FFFh, as defined by the
BBSIZ<1:0> bits in the CONFIG4L register (see
Table 5-1).

Boot Block Programming
: Set Table Pointer for configuration byte to be written. Write even/odd addresses.
Enabling the write protection of Configuration bits (WRTC = 0 in CONFIG6H) will prevent further writing of
Configuration bits. Always write all the Configuration bits before enabling the write protection for Configuration
bits.

3.6
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 Table 3-9.

The address must be explicitly written for
each byte programmed. The addresses
can not be incremented in this mode.
