5.2
The
dsPIC33FJ64GS406/606/608/610 Flash program mem-
ory 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 instruc-
tions) at a time, and to program one row or one word at a
time. Table 27-12 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 27-20) 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 27-12).
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 ‘b000000, 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 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.
