The term “Blank Check” means to verify whether the
device has been successfully erased and has no
programmed memory cells. A blank or erased memory
cell reads as a ‘1’. The following memories must be
blank checked:
• All implemented code memory
• All Configuration bits (for their default value)
The Device ID registers (0xFF0000:0xFF0002) can be
ignored by the Blank Check since this region stores
device information that cannot be erased. Additionally,
all unimplemented memory space should be ignored
from the Blank Check.
The QBLANK command is used for the Blank Check. It
determines if the code memory is erased by testing
these memory regions. A ‘BLANK’ or ‘NOT BLANK’
response is returned. The READD command is used to
read the Configuration registers. If it is determined that
the device is not blank, it must be erased (see
Section 5.4 “Chip

5.6.1
The panel architecture for the Flash code memory
array consists of up to 128 rows of thirty-two, 24-bit
instructions. Each panel stores up to 4K instruction
words. Each dsPIC30F SMPS device has one memory
panel (see
TABLE 5-2:
5.6.2
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
words of a dsPIC30F2020 device are programmed.
First, the number of commands to send (called
‘RemainingCmds’ in the flowchart) is set to 128 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. After the first command is
processed

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.
5.6.3
After programming the code memory, the contents of
memory can be verified to ensure that programming
was successful. Verification requires code memory to
be read back and compared against the copy held in
the programmer’s buffer.
The READP command can be used to read back all the
programmed code memory.
Alternatively, you can have the programmer perform
the verification once the entire device is programmed
using a checksum computation, as described in
Section 6.6 “Checksum
