DMA CONTROLLER  
DMA TRANSFER COUNT REGISTERS  
The DMA transfer count registers contain the 24-bit current count value of the number of DMA transfers  
completed for GDMA channels 0 and 1.  
The count value is always decremented by one for each completed DMA operation, regardless of the GDMA data  
transfer width or four-data burst mode.  
NOTE  
At the 4-data burst mode, actual transfer data size will be "Transfer Count x4."
