PIC24FJ128GA FAMILY
4.2
The PIC24 Flash program memory array is organized
into rows of 64 instructions or 192 bytes. RTSP allows
the user to erase blocks of eight rows (512 instructions)
at a time, and to program one row at a time. The 8-row
erase blocks and single-row write blocks 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 in sequential order. The
instructions words loaded must always be from a group
of 64 boundaries.
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 set-
ting 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
(2 instruction cycles), because only the buffers are writ-
ten. A programming cycle is required for programming
each row.

RTSP Operation
Advance Information
4.3
There are two SFRs used to read and write the
program Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 4-1) 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 must consecutively write 55h and AAh to the
NVMKEY register. Refer to Section 4.4 “Programming
Operations” for further details.
4.4
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. A programming operation is nominally 4 ms in
duration and the processor stalls (waits) until the oper-
ation is finished. Setting the WR bit (NVMCON<15>)
starts the operation, and the WR bit is automatically
cleared when the operation is finished.
