7.0
In the hex file there are two bytes per program word
stored in the Intel
LSB first, MSB second. Because there are two bytes
per word, the addresses in the hex file are 2x the
address
Configuration Word 1 is stored at 2007h on the
PIC16F72X/PIC16LF72X. In the hex file this will be at
location 400Eh-400Fh).
7.1
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.

(Example:
= 2534h + (2AC3h and 3F7Fh) + (3FEFh and 0030h)
= 2534h + 2A43h + 0020h
= 4F97h

7.2
If a device ID is present in the hex file at 400Ch-400Dh
(2006h on the part), the programmer should verify the
device ID/revision against the value read from the part.
On a mismatch condition, the programmer should
generate a warning message.
7.3
The checksum is calculated by two different methods,
dependent on the setting of the CP Configuration bit.
7.3.1
With the code protection disabled, the checksum is
computed by reading the contents of the PIC16F72X/
PIC16LF72X program memory locations and adding
up the program memory data, starting at address
0000h, up to the maximum user addressable location
(e.g., 1FFFH for the PIC16F726). Any Carry bit
exceeding 16 bits are neglected. Additionally, the rele-
vant bits of the Configuration Words are added to the
checksum. All unused Configuration bits are masked to
‘0’.
