CODE PROTECTION
Code protection is controlled using the CP bit in
Configuration Word 1. When code protection is
enabled, all program memory locations (0000h-7FFFh)
read as all ‘0’. Further programming is disabled for the
program memory (0000h-7FFFh).
Data memory is protected with its own Code-Protect bit
(CPD). When data code-protection is enabled (CPD = 0),
all data memory locations read as ‘0’. Further
programming is disabled for the data memory. Data
memory can still be programmed and read during
program execution.
The user ID locations and Configuration Words can be
programmed and read out regardless of the code
protection settings.
6.1
Program Memory
Code protection is enabled by programming the CP bit
in Configuration Word 1 register to ‘0’.
The only way to disable code protection is to use the
Bulk Erase Program Memory command.
6.2
Data Memory
Data memory protection is enabled by programming
the CPD bit in Configuration Word 1 register to ‘0’.
The only way to disable code protection is to use the
Bulk Erase Program Memory command.

HEX FILE USAGE
In the hex file there are two bytes per program word
stored in the Intel INHX32 hex format. Data is stored
LSB first, MSB second. Because there are two bytes
per word, the addresses in the hex file are 2x the
address
in
program
memory.
(Example:
The
Configuration Word 1 is stored at 8007h on the
PIC16F193X/PIC16LF193X. In the hex file this will be
referenced as 1000Eh-1000Fh).
7.1
Configuration Word
To allow portability of code, it is strongly recommended
that the programmer is able to read the Configuration
Words and user ID locations from the hex file. If the
Configuration 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 should be included.
7.2
Device ID and Revision
If a device ID is present in the hex file at
1000Ch-1000Dh (8006h on the part), the programmer
should verify the device ID (excluding the revision)
against the value read from the part. On a mismatch
condition the programmer should generate a warning
message.
7.3
Data EEPROM
The programmer should be able to read data memory
information from a hex file and write data memory
contents to a hex file.
The physical address range of the 256 data memory is
0000h-00FFh. However, these addresses are logically
mapped to address 1E000h-1E1FFh in the hex file.
This provides a way of differentiating between the data
and program memory locations in this range. The
format for data memory storage is one data byte per
address location, LSb aligned.
Note:
To ensure system security, if CPD bit = 0,
the Bulk Erase Program Memory command
will also erase data memory.
