6.0
The dsPIC30F family of devices contains internal
program Flash memory for executing user code. There
are two methods by which the user can program this
memory:
1.
2.
6.1
dsPIC30F devices can be serially programmed while in
the end application circuit. This is simply done with two
lines for Programming Clock and Programming Data
(which are named PGC and PGD, respectively), 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 may erase program memory,
32 instructions (96 bytes) at a time, and can write
program memory data, 32 instructions (96 bytes) at a
time.
6.3
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
Word or Byte mode.
The TBLRDH and TBLWTH instructions are used to read
or write to bits<23:16> of program memory. TBLRDH
and TBLWTH can access program memory in Word or
Byte mode.
A 24-bit program memory address 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
