I try to interface uPSD3334 with 24C256 i2c eeprom.

I used upsd3300_i2c.c routine for interfacing software.

My eeprom address is 0xA0;

Highbyte location = 0x00;

Lowbyte location = 0x00;

I can write to the eeprom location without any problem.

Problem occured when I try to read the data.

It seems to read the first data from the next location (Lowbyte0x01) instead of Lowbyte=0x00;
