dma_start(channel, mode, addressA, addressB, count);
Channel- The channel used in the DMA transfer
mode - The mode used for the DMA transfer.
addressA- The start RAM address of the buffer to use located within the DMA
RAM bank.
addressB- If using PING_PONG mode the start RAM address of the second
buffer to use located within the DMA RAM bank.
void
Starts the DMA transfer for the specified channel in the specified mode of operation.
