Slave does not ACK address

Hi foks,

I am trying to comunicate with EEPROM memory (Atmel 24C32) using I2C interface and MSP430F2621. I have done initialization of I2C interface, but when I am trying to address slave device (EEPROM), it does not ACK that.

void i2cInit() {
    P3SEL |= 0x06; //pin selection

    P3REN |= 0x06; //activationg pull-ups on these pins

    UCB0CTL1 = UCSWRST; //reset

    UCB0CTL0 = UCMODE_3 + UCSYNC + UCMST;
    UCB0CTL1 = UCSSEL_2 + UCSWRST;
    UCB0BR0 = 0x12; // fSCL = SMCLK/12 = ~100kHz
    UCB0BR1 = 0x00;

    UCB0CTL1 &= ~UCSWRST; //enable

}

int eepromWriteByte(unsigned int addr, unsigned char data) {
    int transmited = 0;
    do {
        transmited = 1;
        UCB0I2CSA = 0x50;// address of EEPROM
        UCB0CTL1 |= UCTR + UCTXSTT; //want to write + start bit
        while (UCB0CTL1 & UCTXSTT) {;}//!!!!STUCKED HERE!!!!

       if ((UCB0STAT & UCNACKIFG) != 0) {
            UCB0CTL1 |= UCTXSTP; //stop bit
            transmited = 0;
        }
    } while (!transmited); //retransmit

}

int main() {
    WDTCTL = WDTPW + WDTHOLD; //stoping watchdog

    i2cInit();

    eepromWriteByte(0x0000,0x13);

}

I am stucked at point in eepromWriteByte in while cycle after sending START BIT. Look in code.

I checked all the pins on EEPROM with multimetr, VCC +3.3V on VCC, SDA, SCL after running my app, so memory is connected correctly I think.

Any ideas?

Thanks a lot
