dsPIC30F Flash Programming Specification
11.8
Writing Code Memory
The procedure for writing code memory is similar to the
procedure for clearing the Configuration registers,
except that 32 instruction words are programmed at a
time. To facilitate this operation, working registers
W0:W5 are used as temporary holding registers for the
data to be programmed.
Table 11-8 shows the ICSP programming details,
including the serial pattern with the ICSP command
code, which must be transmitted Least Significant bit
first using the PGC and PGD pins (see Figure 11-2). In
Step 1, the Reset vector is exited. In Step 2, the
NVMCON register is initialized for single-panel
programming of code memory. In Step 3, the 24-bit
starting destination address for programming is loaded
into the TBLPAG register and W7 register. The upper
byte of the starting destination address is stored to
TBLPAG, while the lower 16 bits of the destination
address are stored to W7.
To minimize the programming time, the same packed
instruction format that the programming executive uses
is utilized (Figure 8-2). In Step 4, four packed
instruction words are stored to working registers
W0:W5 using the MOV instruction and the read pointer
W6 is initialized. The contents of W0:W5 holding the
packed instruction word data is shown in Figure 11-4.
In Step 5, eight TBLWT instructions are used to copy the
data from W0:W5 to the write latches of code memory.
Since code memory is programmed 32 instruction
words at a time, Steps 4 and 5 are repeated eight times
to load all the write latches (Step 6).
After the write latches are loaded, programming is
initiated by writing to the NVMKEY and NVMCON
registers in Steps 7 and 8. In Step 9, the internal PC is
reset to 0x100. This is a precautionary measure to
prevent the PC from incrementing into unimplemented
memory when large devices are being programmed.
Lastly, in Step 10, Steps 2-9 are repeated until all of
code memory is programmed.
