5.0
The
dsPIC33FJ16MC101/102 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)

ICSP allows a device to be serially programmed while
in the end application circuit. This is done with two lines
for 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 users to manufac-
ture boards with unprogrammed devices, and then pro-
gram 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 in a single
program memory word, and erase program memory in
blocks or ‘pages’ of 512 instructions (1536 bytes).
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.
