`BCM2838_DMA_TI_PERMAP = ($1F shl 16);`	Peripheral Mapping (Indicates the peripheral number (1-31) whose ready signal shall be used to control the rate of the transfers)
`BCM2838_DMA_TI_WAITS = ($3E shl 21);`	Add Wait Cycles (This slows down the DMA throughput by setting the number of dummy cycles burnt after each DMA read or write operation is completed)
`BCM2838_DMA_TI_NO_WIDE_BURSTS = (1 shl 26);`	Don't Do wide writes as a 2 beat burst (This prevents the DMA from issuing wide writes as 2 beat AXI bursts. This is an inefficient access mode, so the default is to use the bursts.)
