5.0
The dsPIC33FJXXXGPX06A/X08A/X10A devices con-
tain 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:
1.
2.
ICSP allows a dsPIC33FJXXXGPX06A/X08A/X10A
device to be serially programmed while in the end
application circuit. This is simply 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 customers to manu-
facture 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
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.
