3.2
Programming code memory is accomplished by first
loading data into the write buffer and then initiating a
programming sequence. The write buffer for all devices
in the PIC18F97J60 family is 64 bytes; it can be
mapped to any integral boundary of 64 bytes,
beginning at 000000h. The actual memory write
sequence takes the contents of this buffer and
programs the 64 bytes of code memory that contains
the Table Pointer.
Write buffer locations are not cleared following a write
operation; the buffer retains its data after the write is
complete. This means that the buffer must be written
with 64 bytes on each operation. If there are locations
in the code memory that are to remain empty, the
corresponding locations in the buffer must be filled with
FFFFh. This avoids rewriting old data from the previous
cycle.
The programming duration is internally timed. After a
Start Programming command is issued (4-bit com-
mand, ‘1111’), a NOP is issued, where the 4th PGC is
held high for the duration of the programming time, P9.

Step 1: Enable writes.
Step 2: Load write buffer.
Step 3: Repeat for all but the last two bytes. Any unused locations should be filled with FFFFh.
Step 4: Load write buffer for last two bytes.
To continue writing data, repeat steps 2 through 4, where the Address Pointer is incremented by 2 at each iteration of the loop.

PIC18F97J60 FAMILY
The code sequence to program a PIC18F97J60 family
device is shown in Table 3-3. The flowchart shown in
Figure 3-5 depicts the logic necessary to completely
write a PIC18F97J60 family device. The timing diagram
that details the Start Programming command and
parameter P9 is shown in Figure 3-6.
Note 1: To maintain the endurance specification
Core Instruction
2: The TBLPTR register must point to the
of the Flash program memory cells, each
64-byte block of program memory should
never be programmed more than once
between erase operations. If any byte
within a 64-byte block of program
memory is written, that entire block must
not be written to again until a Bulk Erase
on the part, or a Row Erase on the row
containing the modified 64-byte block,
has been performed.
same region when initiating the program-
ming sequence as it did when the write
buffers were loaded.
