2.1.9 Read-DMA (C8h)
The Read-DMA command allows the host to read data using the DMA transfer protocol. 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.
2.1.10 Read-Multiple (C4h)
The Read-Multiple command executes similarly to the Read-Sector command with the exception that
interrupts are issued only when a block containing the counts of sectors defined by the Set-Multiple command
is transferred.
