The PIC24FV32KA304 of devices contains internal
Flash program memory for storing and executing appli-
cation code. The memory is readable, writable and
erasable when operating with V
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 PIC24FV32KA304 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
E
manufacture boards with unprogrammed devices and
then program the microcontroller just before shipping
the product. This also allows the most recent firmware
or custom firmware to be programmed.

Run Time Self Programming (RTSP) is accomplished
using TBLRD (table read) and TBLWT (table write)
instructions. With RTSP, the user may write program
memory data in blocks of 32 instructions (96 bytes) at
a time, and erase program memory in blocks of 32, 64
and 128 instructions (96,192 and 384 bytes) at a time.
The NVMOP<1:0> (NVMCON<1:0>) bits decide the
erase block size.

Regardless of the method used, Flash memory
programming is done with the table read and 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
depicted 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.
