I2C interfacing problemeith eeprom 24c32a

I2C interfacing problem with eeprom 24c32a

hai
I have interfaced an EEPROM 24C32A with 89c51.
I can send data into EEPROM, but can't read the same
this is my asm & circuit. Plz help me.............

SDA EQU P1.1
SCL EQU P1.0

ORG 00H
AJMP MAIN
ORG 30H

MAIN: MOV R7,#08H //SEND COUNT//
MOV R6,#08H //RECEIVE COUNT//
SETB P3.0
MOV R2,#32H //STORE RECEIVED DATA FROM EEPROM//
LOCK1: JB P3.0,LOCK1
;SJMP LOCK2
//32 BYTES CONTINEOUS WRITE//
ACALL I2C_START //START I2C//

//WRITES THE DATA INTO SLAVE//

ACALL I2C_CONTROL_BYTE_W //START+SLAVE ADDRESS+DEVICE SELECT+ACK//
ACALL I2C_SEND //SEND DATA TO SLAVE//
ACALL SLAVE_ACK_CHECK //WAIT FOR ACK FROM SLAVE//
ACALL I2C_ADDRESS_BYTE_H //HIGHER ORDER ADDRESS BYTE//

//READ THE DATA FROM THE SLAVE//

where is the circuit diagram

If you are doing byte read then try to read with NACK..
If sequential read then all other read with ACK except last one, that one should be read with NACK...

try this code. It works.
