5.0
The PIC24HJ32GP202/204 and PIC24HJ16GP304
devices contain internal Flash program memory to
store and execute 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
PIC24HJ16GP304 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

customers to manufacture boards with unprogrammed
devices and then program the microcontroller 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 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
The TBLRDL and the TBLWTL instructions are used to
read or write to the 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.
