5.0
For PIC16F88X, once the CP bit is programmed to ‘0’,
all program memory locations read all ‘0’s. Further
programming is disabled for the entire program
memory.
Data memory is protected with its own Code-Protect bit
(CPD). When enabled, the data memory can still be
programmed and read using the EECON1 register
(See the applicable data sheet for more information).
The user ID locations and the Configuration Word can
be programmed and read out regardless of the state of
the CP and CPD bits.
5.1
It is recommended to use the procedure in Figure 3-21
to disable code protection of the device. This sequence
will erase the program memory, data memory, Configu-
ration Word (0x2007-0x2008) and user ID locations
(0x2000-0x2003). The Calibration Words (0x2009) will
not be erased.
5.2
To allow portability of code, the programmer is required
to read the Configuration Words and user ID locations
from the hex file when loading the hex file. If Configura-
tion Words information was not present in the hex file,
a simple warning message may be issued. Similarly,
while saving a hex file, Configuration Words and user
ID information must be included. An option to not
include this information may be provided.
Specifically for the PIC16F88X, the data memory
should also be embedded in the hex file (see
Section 5.3.2 “Embedding Data Memory Contents
In Hex File”).
Microchip Technology Incorporated feels strongly that
this feature is important for the benefit of the end
customer.

To ensure system security, if CPD bit = 0,
Bulk Erase Program Memory command
will also erase data memory.

5.3.1
Checksum is calculated by reading the contents of the
PIC16F88X memory locations and adding up the
opcodes up to the maximum user addressable location,
(e.g., 0x1FFF for PIC16F886/887). Any carry bits
exceeding 16 bits are neglected. Finally, the Configura-
tion Words (appropriately masked) are added to the
checksum. Checksum computation for the PIC16F88X
devices is shown in Table 5-1.
The checksum is calculated by summing the following:
• The contents of all program memory locations
• The Configuration Words, 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 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 calculating a checksum by reading a
device, the entire program memory can simply be read
and summed. The Configuration Words and user ID
locations can always be read regardless of code-
protect setting.
Note:
Checksum Computation
CHECKSUM
Some older devices have an additional
value added in the checksum. This is to
maintain compatibility with older device
programmer checksums.
