How to detect TCP3D driver 's Pause state ?

Hi,

I've run pdk_C6670_1_0_0_20\packages\ti\drv\tcp3dExampleProjects on TMS320C6670. The driver's pause state detection has to be realized by running start function all the time in a while(1) loop , which costs the core much time.How can I avoid doing so.

Can the TCP3D generates a signal itself when it runs into Pause state so that I can only call start function at that time ?

while ( 1 )  // at Line 745 in tcp3d_example_main.c 

    {

        /* Pending on Semaphore to run the loop */

        Semaphore_pend(semSendWait, BIOS_WAIT_FOREVER);

        /* Received both the completion events, so exit send task */

        if ( tcp3dEventCntr >= 2 ) 

        {

            break;

        } else if ( tcp3dEventCntr == 1 )

        {

            /* one code block test case */

            if ( codeBlockSet.maxNumCB == 1 )

            {

                break;

            }

            else if ( codeBlockSet.mode == TEST_MODE_SPLIT )

            {

        ................

            }

        }

        if ( TCP3D_DRV_NO_ERR != Tcp3d_start(inst, TCP3D_DRV_START_AUTO) )

        {

            System_printf("Tcp3d_start function returned error\n");

            System_exit(0);

        }

        /* keep trying until finding two end events */

        Semaphore_post(semSendWait);

        pendPauseCntr++;

    }

    /* Last code block decoded - Start the receive task */

    total_clock_end = TSCL;

    Semaphore_post(semRcvStart);

}
