Execution of these commands involves no data transfer.

13.4 DMA Data Transfer Commands

These commands are:

Read DMA

Read DMA Ext

Write DMA

Write DMA 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 HTS5416XXJ9SA00 Final Functional Specification for further details.

13.5 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 4.2 “Native Command Queuing” of “Serial ATA II: Extensions to Serial ATA 1.0a”.
