CCS/ADS122U04: Problem with receiving data

Tool/software: Code Composer Studio

Hello
I have a problem with receiving data from the thermistor. I use IDAC to direct current to the sensor, and ADC`s AIN2/AIN3 inputs to receive data from the the sensor. Gain and IDAC current setting didn`t help. Always get incorrect values.
I use manual mode with counter (without DRDY).

int main(void)
{
    WDTCTL = WDTPW | WDTHOLD;   // stop watchdog timer

    // Disable the GPIO power-on default high-impedance mode to activate
    // previously configured port settings
    PM5CTL0 &= ~LOCKLPM5;
    FRCTL0 = FRCTLPW | NWAITS_1;

    P4DIR = BIT0;           //setting P1.0 as output
    P4OUT = BIT0;

    CS_init ();

    UART_init();

    reset();

    reg0_init();
    reg1_init();
    reg2_init();
    reg3_init();

    UART_transmit();

}
