5.0
The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X, and PIC24EPXXXGP/MC20X 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
alternate programming pin pairs: PGECx/PGEDx), and
three other lines for power (V
Master Clear (MCLR). This allows customers to
manufacture boards with unprogrammed devices and
then program the device 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 a single
program memory word, and erase program memory in
blocks or ‘pages’ of 1024 instructions (3072 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.
