DOWNLOADING A DATA
BLOCK
To program a block of data to the PIC32MX device, it
must first be loaded into SRAM.
12.1
Without the PE
To program a block of memory without the use of the
PE, the block of data must first be written to RAM. This
method requires the programmer to transfer the actual
machine instructions with embedded (immediate) data
for writing the block of data to the devices internal RAM
memory.
FIGURE 12-1:
DOWNLOADING DATA
WITHOUT THE PE
The following steps are required to download a block of
data:
1.
XferInstruction
(op code).
2.
Repeat Step 1 until the last instruction is
transferred to CPU.

12.2
With the PE
When using the PE the steps in Section 12.0 “Down-
Flash Row Write” are handled in two single commands:
ROW_PROGRAM
and PROGRAM.
The ROW_PROGRAM command programs a single row of
Flash data, while the PROGRAM command programs
multiple rows of Flash data. Both of these commands
bufAddr = RAM Buffer Address
Write 32-bit Immediate
Increment bufAddr
Done
No
Data to bufAddr
Op code
Instruction
Step 1: Initialize SRAM Base Address to
0xA000_0000
3c10a000
lui
$s0, 0xA000;
Step 2: Write the entire row of data to be
programmed into system SRAM.
3c08<DATA>
3508<DATA>
ae08<OFFSET>
lui
$t0, <DATA(31:16)>;
ori
$t0, <DATA(15:0)>;
sw
$t0, <OFFSET>($s0);
// OFFSET increments by 4
Step 3: Repeat Step 2 until one row of data has
been loaded.
