Figure 5.5 Register - Device to Host FIS layout

The Register - Device to Host FIS is used when information concerning the Shadow Register Block in the host adapter is updated. This FIS indicates that the device has completed a command operation. Furthermore, this is a mechanism for changing information concerning the Shadow Register Block of the host adapter.

I - If this bit is set, an interrupt request is issued to the host system.

5.2.3.4 DMA Active - Device to Host
						The DMA Active - Device to Host FIS has the following layout:

	3	3		2	2		2	2		2	2	2	2		2	2	1	1		1	1	1	1	1	1	1	1	9	8	7	6	5	4	3	2	1	0

Figure 5.6 DMA Active - Device to Host FIS layout

The host uses the DMA Active - Device to Host FIS layout. This FIS instructs the host to continue transferring DMA data from the host to the device.
