The dsPIC33FJ32MC302/304, dsPIC33FJ64MCX02/
X04 and dsPIC33FJ128MCX02/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)

programming clock and programming data (one of the

three other lines for power (V
Master Clear (MCLR). 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
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.
