The term “Blank Check” implies verifying if 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 (FF0002h:FF0000h) can be
ignored by the Blank Check as 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 by 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 device.

4.5.1
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.

Figure 4-5 illustrates an example flowchart for
programming code memory. In this example, all 5.5K
instruction words of a PIC24FXXKAXXX device are
programmed.
• First, the number of commands to send (titled
• Next, one write block in the device is programmed
• After the first command is processed successfully,
Since there are more PROGP commands to be sent,
‘BaseAddress’ is incremented by 40h 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. Special
handling should not be performed when a panel
boundary is crossed.
‘RemainingCmds’ in the flowchart) is set to 176,
and the destination address (called
‘BaseAddress’) is set to ‘0’.
with a PROGP command. Each PROGP command
contains data for one row of code memory of the
PIC24FXXKAXXX device.
‘RemainingCmds’ is decremented by 1 and
compared with 0.
