The term “Blank Check” implies verifying that the
device has been successfully erased and has no
programmed memory locations. A blank or erased
memory location is always read as ‘1’.
The Device ID registers (0xFF0000:0xFF0002) can be
ignored by the Blank Check since this region stores
device information that cannot be erased. The device
Configuration registers are also ignored by the Blank
Check. 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. If it is determined that the device
is not blank, it must be erased before attempting to
program the chip.

Code memory is programmed with the PROGP
command. PROGP programs one row of code memory
starting from the memory address specified in the
command. The number of PROGP commands required
to program a device depends on the number of write
blocks that must be programmed in the device.
A flowchart for programming code memory is illustrated

the
‘RemainingCmds’ in the flowchart) is set to 1368 and
the destination address (called ‘BaseAddress’) is set to
‘0’. Next, one write block in the device is programmed
with a PROGP command. Each PROGP command
contains data for one row of code memory of the
dsPIC33F/PIC24H.
processed
decremented by ‘1’ and compared with ‘0’. Since there
are more PROGP commands to send, ‘BaseAddress’ is
incremented by 0x80 to point to the next row of
memory.
On the second PROGP command, the second row is
programmed. This process is repeated until the entire
device is programmed.
