I know this kind of questions are hard to answer but I can
answer to my own question.

using CCS compiler:

#ROM {4,5,6,7}; so on 

using hi-tech compiler
__EEPROM_DATA( 0x01, 0x02, 0, 0, 0, 0, 0); so on

Subject: [PIC ] Writing to EEPROM without effecting checksum


William,

thank you for your quick replay now I know \ what is it for.
New question!

I am having problem with programming EEPROM without effecting checksum.
There is an existing example written in Hi-Tech C that using
__EEPROM_DATA( 0x01, 0x02, 0, 0, 0, 0, 0);
it can write in EEPROM right after origin without effecting pic's checksum

I am using CCS C and the only command I can use is
WRITE_EEPROM(address, value); and it must be after main()
the problem with this is after I change the content of EEPROM pic's
checksum  changes.

My question is how can I write to EEPROM without effecting the pic's 
checksum
like Hi-Tech did it.  any idea ?


thanks

Andre
