The Boot Block segment is programmed in exactly the
same manner as the ID locations (see Section 3.4).
Multi-panel writes must be disabled so that only
addresses in the range 0000h to 01FFh will be written.
The code sequence detailed in Figure 3-6 should be
used, except that the address data used in “Step 2” will
be in the range 000000h to 0001FFh.

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
