Hi.
In my project i use 80C552 uc. I need to use 24C02 I2C EEPROM. I've try to use Philips code (gived by philips in 80c552 appication note - this one witch work on first memory page).
When i try to write EEPROM it work fine.
I do this like that:

MOV MTD,#00H ; Subadress
MOV MTD+1,#0FFH ; Write 0FFH
MOV SLA,#0A0H ; EEPROM adress
MOV NUMBYTMST,#02 ; SeÏ
