The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices contain internal Flash program memory for
storing and executing application code. The memory is
readable, writable and erasable during normal operation
over the entire V
Flash memory can be programmed in two ways:
• In-Circuit Serial Programming™ (ICSP™)
• Run-Time Self-Programming (RTSP)

programmed while in the end application circuit. This is
done with two lines for programming clock and

pin pairs: PGECx/PGEDx, and three other lines for
power (V
This allows customers to manufacture boards with
unprogrammed devices and then program the digital

signal controller just before shipping the product. This
also allows the most recent firmware or a custom
firmware to be programmed.
RTSP is accomplished using TBLRD (table read) and
TBLWT (table write) instructions. With RTSP, the user
application can write program memory data, either in
blocks or ‘rows’ of 64 instructions (192 bytes) at a time,
or a single program memory word, and erase program
memory in blocks or ‘pages’ of 512 instructions
(1536 bytes) at a time.
5.1
Regardless of the method used, all programming of
Flash memory is done with the table read and table
write instructions. These allow direct read and write
access to the program memory space from the data
memory while the device is in normal operating mode.
The 24-bit target address in the program memory is
formed using bits<7:0> of the TBLPAG register and the
Effective Address (EA) from a W register specified in
the table instruction, as shown in Figure 5-1.
The TBLRDL and the TBLWTL instructions are used to
read or write to bits<15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
The TBLRDH and TBLWTH instructions are used to read
or write to bits<23:16> of program memory. TBLRDH
and TBLWTH can also access program memory in Word
or Byte mode.
