Gerhard,

I was wondering can I use your assembly code before main()?

     #asm
     org 0xF000000     ;EEPROM start address
     de 0x59,0x43,0xFF,0x67,0xFF,0x77,0xFF,0x76
     de 0xF5F,0x65,0xFF,0xFF,0xFF,0x55,0xAA,0xAB
     #endasm

for some reason Mplab doesn't recognize 
#ROM 0x2100={0x01,0x02,and so on} using CCS compiler
I was wondering to replace it with assembly it looks
pretty good.


thanks

Andre

This is how EEPROM is set in MPASM

     org 0xF000000     ;EEPROM start address
     de 0x59,0x43,0xFF,0x67,0xFF,0x77,0xFF,0x76
     de 0xF5F,0x65,0xFF,0xFF,0xFF,0x55,0xAA,0xAB
