How to use the IIR-Accelerator in continuous-mode ADSP-SC584


I´m using the ADZS-SC584-EZLITE with the ADSP-SC584 and CrossCore 2.8.3.

I found the Example-Project IIR_Filter_Response for the ADSP-SC589. I changed the Processorsetting and was able to run the Project.

 But the Program does only a single filter cycle for a defined Winow_Size. I can restart the IIR-Filter-Channel but the Filter starts from the beginning. So the start up of the Filter is seen in the beginning of the OutputChanel. Is there a way to do a continuous Filtering without start up the Fitler over and over. 

Is there a way to save the state of the Filter or something in this way?

Please help
