EDMA3 linked transfer

Hello,

I am using linked transfer in EDMA3. The datasheet says that when BCNT==1 && CCNT==1, the last TR(transfer request) is submitted and the param set should be updated with the linked param set. However, in my case, the last TR is submitted and param set is updated when BCNT==0 and CCNT==1, resulting in an extra TR. 

Does anyone know why my BCNT count decrements till 0 and later the update occurs?
