SSP DMA interrupt to early

Wat's wrong? I work on LPC1768 and i wrote a routine to receive SSP data  over DMA in master mode. All thinks work fine but the job done  interrupt from the DMA engine (terminal count interrupt) is always 4 byte to early. I guess that's   because the half full receive FIFO (8Byte/2). I need a interrupt only  after receive job is complete. Do anyone know a trick to correct this  behaviour.
