MCF52259 - Reading ADC-Modul with DMA-Request (DMA-Timer)

i want to read the ADRSLTn-Registers with a DMA-Request. I used an DMA-Timer which request periodically a DMA-Transfer. The problem is that the RDY-Bits in the ADSTAT no be cleared. So i get always the same result. The ADC runs in loop-Mode with fastest speed, so an complete measurement is much faster then the DMA-Timer. Can everyone help me? Thanks.
