3.5
The Boot Block segment is programmed in exactly the
same manner as the ID locations (see Section 3.4 “ID
Location Programming”). Multi-panel writes must be
disabled so that only addresses in the range, 0000h to
07FFh, will be written.
The code sequence detailed in Table 3-7 should be
used, except that the address data used in “Step 2” will
be in the range, 000000h to 0007FFh.
TABLE 3-8:
DS39606E-page 20
Step 1: Direct access to configuration memory.
Step 2: Position the program counter.
Step 3: Set Table Pointer for configuration byte to be written. Write even/odd addresses.
Step 4: Execute four NOPs.

Boot Block Programming
If the code protection bits are programmed while the program counter resides in the same block, then the interaction of
code protection logic may prevent further table write. To avoid this situation, move the program counter outside the
code protection area (e.g., GOTO 100000h).
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
configuration locations is shown in Table 3-8.
