6.0
For PIC12F609/12F615/16F610/16F616/PIC12HV609/
12HV615/16HV610/16HV616, once the CP bit is
‘0’s. The user ID locations and the Configuration Word
read out in an unprotected fashion. Further programming
is disabled for the entire program memory.
The user ID locations and the Configuration Word can
be programmed regardless of the state of the CP bit.
6.1
It is recommended to use the procedure in Figure 4-14
to disable code protection of the device. This sequence
will erase the program memory, Configuration Word
(0x2007) and user ID locations (0x2000-0x2003). The
Calibration Word (0x2008) will not be erased.
6.2
To allow portability of code, the programmer is required
to read the Configuration Word and user ID locations
from the hex file when loading the hex file. If Configura-
tion Word information was not present in the hex file, a
simple warning message may be issued. Similarly,
while saving a hex file, Configuration Word and user ID
information must be included. An option to not include
this information may be provided.
Microchip Technology Incorporated feels strongly that
this feature is important for the benefit of the end
customer.

6.3.1
Checksum is calculated by reading the contents of the
PIC12F609/12F615/16F610/16F616/PIC12HV609/
12HV615/16HV610/16HV616 memory locations and
adding up the opcodes up to the maximum user
addressable location (e.g., 0x7FF for the PIC16F616).
Any carry bits exceeding 16 bits are neglected. Finally,
the Configuration Word (appropriately masked) is
added to the checksum. Checksum computation for the
PIC12F609/12F615/16F610/16F616/PIC12HV609/
12HV615/16HV610/16HV616 devices is shown in
Table 6-1.
The checksum is calculated by summing the following:
• The contents of all program memory locations
• The Configuration Word, appropriately masked
• Masked user ID locations (when applicable)
The Least Significant 16 bits of this sum is the
checksum.
Table 6-1 describes how to calculate the checksum for
each device. Note that the checksum calculation differs
depending on the code-protect setting. Since the
program memory locations read out zeroes when code-
protected, the table describes how to manipulate the
actual program memory values to simulate values that
would be read from a protected device. When calculat-
ing a checksum by reading a device, the entire program
memory can simply be read and summed. The
Configuration Word and user ID locations can always
be read regardless of code-protect setting.
Note:

CHECKSUM
Some older devices have an additional
value added in the checksum. This is to
maintain compatibility with older device
programmer checksums.
