dsPIC33FJ32GP202/204 and dsPIC33FJ16GP304
5.2
The
dsPIC33FJ16GP304 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. 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 22-18, “AC Characteristics: Internal RC
Accuracy”) and the value of the FRC Oscillator Tuning
register (see Register 8-4). 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 22-12, “DC
Characteristics: Program Memory”).
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 8-4) 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: Flash Memory Control Register
• NVMKEY: Nonvolatile Memory Key Register
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
consecutively write 0x55 and 0xAA to the NVMKEY
register.
