thanks anyway

DYTA EQU 51H
ADRES EQU 52H

MOV ADRES,#10H
MOV DYTA,#32H


what does this code means?

and

EEPROM_READ_ADDR:
MOV A,#10100001B
LCALL WRITE1
RET

EEPROM_WRITE_ADDR:
MOV A,#10100000B
LCALL WRITE
RET

if i want to access the other i2c device with address A1=0 and A0=1, am i just change the second bit in that code ?
the code should be

EEPROM_READ_ADDR:
MOV A,#10100011B
LCALL WRITE1
RET

EEPROM_WRITE_ADDR:
MOV A,#10100010B
LCALL WRITE
RET

am i right?
sorry, this is not my homework
i'm just curious
