5.2
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 Flash program memory
array is organized into rows of 64 instructions or 192
bytes. RTSP allows the user application to erase a
page of memory, which consists of eight rows (512
instructions) at a time, and to program one row or one
word at a time. Table 28-12 shows typical erase and
programming times. The 8-row erase pages and single
row write rows are edge-aligned from the beginning of
program memory, on boundaries of 1536 bytes and
192 bytes, respectively.
The program memory implements holding buffers that
can contain 64 instructions of programming data. Prior
to the actual programming operation, the write data
must be loaded into the buffers sequentially. The
instruction words loaded must always be from a group
of 64 boundary.
The basic sequence for RTSP programming is to set up
a Table Pointer, then do a series of TBLWT instructions
to load the buffers. Programming is performed by
setting the control bits in the NVMCON register. A total
of 64 TBLWTL and TBLWTH instructions are required
to load the instructions.
All of the table write operations are single-word writes
(two instruction cycles) because only the buffers are
written.

programming operation is finished.
The programming time depends on the FRC accuracy
(see Table 28-19) and the value of the FRC Oscillator
Tuning register (see Register 9-4). Use the following
formula to calculate the minimum and maximum values
for the Row Write Time, Page Erase Time, and Word
Write Cycle Time parameters (see Table 28-12).
EQUATION 5-1:
For example, if the device is operating at +125°C,
the FRC accuracy will be ±5%. If the TUN<5:0> bits
(see Register 9-4) are set to ‘b111111, the
Minimum Row Write Time is:
and, the Maximum Row Write Time is:
Setting the WR bit (NVMCON<15>) starts the opera-
tion, and the WR bit is automatically cleared when the
operation is finished.
5.4
Two SFRs are used to read and write the program
Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 5-1) controls which
blocks are to be erased, which memory type is to be
programmed and the start of the programming cycle.
NVMKEY (Register 5-2) is a write-only register that is
used for write protection. To start a programming or erase
sequence, the user application must consecutively write
0x55 and 0xAA to the NVMKEY register. Refer to
Section 5.3 “Programming Operations” for further
details.
