Execution of these commands involves no data transfer.
DMA Data Transfer Commands
These commands are:
 Read DMA
 Read DMA Ext
 Read Log DMA Ext
 Write DMA
 Write DMA Ext
 Write Log DMA Ext
 Write DMA FUA Ext
Initiation of the DMA transfer commands is identical to the Read Sector or Write Sector commands except
that the host initializes the slave-DMA channel prior to issuing the command.
The DMA protocol allows high performance multi-tasking operating systems to eliminate processor
overhead associated with PIO transfers.
Refer Functional Specification part for further details.
First-parity DMA Commands
These commands are:
 Read FPDMA Queued
 Write FPDMA Queued
Execution of this class of commands includes command queuing and the transfer of one or more blocks
of data between the device and the host. The protocol is described in the section 11.14 “FPDMA
Queued command protocol” of “Serial ATA revision 2.6”.
