5. Program the number of 16-bit words that need be transferred in the ATA_DCOUNT register.
6. Program the direction of the transfer in dma_write_to_ram control bit. Set this bit for ATA to RAM
7. Enable the DMA interrupt if wanted.
8. Allow the transfer to start by setting the MISCCR[ATDA] bit.
9. Start the ATA transfer. ATA will now communicate with DMA, and the ATA data automatically
10. The DMA will end the transfer when the ATA_DCOUNT reaches zero. On DMA complete, a
