Need correction for I2c write routine

Hi ,
The following code works fine while reading the contents from the EEPROM (24C04) but does not continuously writes to EEPROM.

Please suggest the correction in this code.

#include <REG52.H>
#include <stdio.h>
#include <intrins.h>

sbit SDA = P2^0;
sbit SCL = P2^1;


#define uchar unsigned char
#define uint unsigned int
#define Byte unsigned char
#define Word unsigned int
#define bool bit
#define true 1
#define false 0


#define SomeNOP(); _nop_();_nop_();_nop_();_nop_();

void contr(uchar);

PCON |= 0x80; // Set bit 7 of the PCON register (SMOD = 1)
SCON = 0x50; // 0101,0000 (Mode 1 and RxD enable)

// Timer #1 overflow rate

TI = 1;


contw(0,'P');
contw(1,'O');


while(1)
{
if(count==5)
count=0;
contr(count++);
}
}
