    Hi,
    I have solved this problem but i notice my code at reading E2PROM goes slow due to which the LED filkers...so, now i am not using E2PROM working on FLASH/program memory of 2000H...
    this syntax don't seems to work but when write any function with @ addr it the code save from that starting addr in memory.
    Code ( (Unknown Language)):
    1. FLASH_WRITE(address,value);
