To allow portability of code, a PIC18FXX80/XX85
programmer is required to read the data EEPROM
information from the HEX file. If data EEPROM infor-
mation is not present, a simple warning message

Checksum
should be issued. Similarly, when saving a HEX file, all
data EEPROM information must be included. An option
to not include the data EEPROM information may be
provided. When embedding data EEPROM information
in the HEX file, it should start at address F00000h.
Microchip Technology Inc. believes that this feature is
important for the benefit of the end customer.
