Command (7)
This command executes in a similar manner to the Read-Sector(s) command except for the following:
- the host initializes the DMA channel prior to issuing the command;
- data transfers are qualified by DMARQ and are performed by the DMA channel;
- the ATA Flash Disk Controller issues only one interrupt per command to indicate that data transfer has
terminated and status is available.
During the DMA transfer phase of a Read-DMA command, the ATA Flash Disk Controller will provide
the status of the BSY bit or the DRQ bit until the command is completed.
