5.0
For the PIC12F510, once code protection is enabled,
all program memory locations 0x40-0x3FE, read all
‘0’s. Program memory locations 0x000-0x03F and
0x3FF are always unprotected. The user ID locations,
backup OSCCAL location and the Configuration Word
read out in an unprotected fashion. It is possible to pro-
gram the user ID locations, backup OSCCAL location
and the Configuration Word after code-protect is
enabled.
5.1
It is recommended that the following procedure be
performed before any other programming is attempted.
It is also possible to turn code protection off (CP = 1)
using this procedure. However, all data within the
program memory will be erased when this
procedure is executed, and thus, the security of the
code is not compromised.

Embedding Configuration Word
and User ID Information in the
Hex File
ERA
Microchip Technology Incorporated feels
strongly that this feature is important for
the benefit of the end customer.
To allow portability of code, the program-
mer 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, then 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.

5.3.1
Checksum is calculated by reading the contents of the
PIC12F510 memory locations and adding up the
opcodes up to the maximum user addressable location
(e.g., 0x3FF for the PIC12F510). Any CARRY bits
exceeding 16 bits are neglected. Finally, the Configura-
tion Word (appropriately masked) is added to the
checksum. Checksum computation for the PIC12F510
is shown in Table 5-1.
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.
The following table describes how to calculate the
checksum for each device.
Note:

CHECKSUM
The checksum calculation differs depend-
ing on the code-protect setting. The
Configuration Word and user ID locations
can always be read regardless of the
code-protect settings.
