DMA Interrupt Register (DIR)

Source data transfer type. Determines the amount of data the DMA controller fetches and buffers data from
the source address. When there are enough bytes to perform a destination data write of the size
programmed in DSTS, the data is written to the destination address. Thus source accesses can be
longword type and destination addresses can be line burst type. In this case, 4 longword reads are
performed followed by an indivisible burst write of 4 longwords.
The most efficient data transfer method is to use longword or line burst transfer types.
