  Read Log DMA Ext 
 Write 

DMA

  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”.
