LAUNCHXL2-RM46: I2C ICRRDY int problem

I am having problem with code.

It doesn't go to i2c interrupt.

I placed Arduino to constantly send information to my TI controller and I want to receive them in interrupt routine.

This is my code for CCS:

sys_main.c:

i2cInit ();

i2cSetOwnAdd (i2cREG1, 0x0A);
i2cSetCount (i2cREG1, 10);
i2cSetDirection (i2cREG1, I2C_RECEIVER);
i2cSetMode (i2cREG1, I2C_MASTER);
i2cEnableNotification (i2cREG1, I2C_RX_INT);
_enable_IRQ ();

while (1);

This is my notification.c code:

i2cReceive (i2cREG1, 10, buff);
while (i2cIsBusBusy (i2cREG1) == true);

while (i2cIsStopDetected (i2cREG1) == 0);

clearSCD (i2cREG1);

This does not work. It never goes to interrupt.

If I place this in main (red color what I add):

i2cInit ();

i2cSetOwnAdd (i2cREG1, 0x0A);
i2cSetCount (i2cREG1, 10);
i2cSetDirection (i2cREG1, I2C_RECEIVER);
i2cSetMode (i2cREG1, I2C_MASTER);
i2cEnableNotification (i2cREG1, I2C_RX_INT);
_enable_IRQ ();

i2cReceive (i2cREG1, 10, buff_main);

while (i2cIsBusBusy (i2cREG1) == true);
while (i2cIsStopDetected (i2cREG1) == 0);

i2cClearSCD (i2cREG1);

while (1);

It receives few information (not 10 as proposed) in main and then enters interrupt.

What is my mistake?

Thanks!
