I2C confusion

Other Parts Discussed in Thread: TMS320F2806

Hi everyone, I've got a question. Are all the acknowledgments handeled by the TI uC itself or do I have to implement ACK in my code too. I have tried to establish communication over I2c. Just read some register, thats it. Instead of using interrupts, I am checking if the rxfifo of ic2 contains any bytes or not, but unfortunatelly the whole process doesn't work out as expected. I have used code from the TI example, only the main .c file has been changed as can be seen below. (TMS320F2806)

Thanks,
