The PIC24FJ256GA110 family of devices contains
internal Flash program memory for storing and execut-
ing application code. The memory is readable, writable
and erasable when operating with V
the regulator is disabled, the V
over 2.25V.
Flash memory can be programmed in three ways:
• In-Circuit Serial Programming™ (ICSP™)
• Run-Time Self-Programming (RTSP)
• Enhanced In-Circuit Serial Programming
ICSP allows a PIC24FJ256GA110 family device to be
serially programmed while in the end application circuit.
This is simply done with two lines for the programming
clock and programming data (which are named PGECx
and PGEDx, respectively), and three other lines for
power (V
This allows customers to manufacture boards with
unprogrammed devices and then program the micro-
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 write program memory data in blocks of 64 instruc-
tions (192 bytes) at a time and erase program memory
in blocks of 512 instructions (1536 bytes) at a time.

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 the TBLPAG<7:0> bits 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.
