Code Memory Programming
5.5.1
OVERVIEW
The Flash code memory array consists of 512 rows of
thirty-two, 24-bit instructions. Each panel stores 16K
instruction words, and each dsPIC30F device has
either 1, 2 or 3 memory panels (see Table 5-2).

PROGRAMMING METHODOLOGY
Code memory is programmed with the PROGP
command. PROGP programs one row of code memory
to the memory address specified in the command. The
number of PROGP commands required to program a
device depends on the number of rows that must be
programmed in the device.
A flowchart for programming of code memory is illus-
trated in Figure 5-3. In this example, all 48K instruction
words of a dsPIC30F6014A device are programmed.
First, the number of commands to send (called
‘RemainingCmds’ in the flowchart) is set to 1536 and
the destination address (called ‘BaseAddress’) is set to
‘0’.
Next, one row in the device is programmed with a
PROGP command. Each PROGP command contains
data for one row of code memory of the
dsPIC30F6014A. After the first command is processed
successfully, ‘RemainingCmds’ is decremented by 1
and compared to 0. Since there are more PROGP
commands to send, ‘BaseAddress’ is incremented by
0x40 to point to the next row of memory.
On the second PROGP command, the second row of
each memory panel is programmed. This process is
repeated until the entire device is programmed. No
special handling must be performed when a panel
boundary is crossed.
