This section provides information on the ATA commands supported by the Zeus SATA SSD. The
commands are issued to the ATA by loading the required registers in the command block with the
supplied parameter, and then writing the command code to the register.

DDMAI0: DMA_in State
DDMAI1: Send_data
DDMAI2: Send_status
Transition DDMAI0:1
Transition DDMAI0:2
Transition DDMAI1:1
Transition DDMAI2:1
When the device has the data ready to transfer a data FIS, the device shall
When the device has transferred all of the data requested by this command
When the data FIS has been transferred, the device shall transition to the
When the FIS has been transmitted, the device shall transition to the DI0:
This state is activated when the device receives a DMA data-in command or
the transmission of one or more data FIS is required to complete the
command. When in this state, the device shall prepare the data for transfer
of a data FIS to the host.
transition to the DDMAI1: Send_data state.
or has encountered an error that causes the command to abort before
completing the transfer of the requested data, then the device shall
transition to the DDMAI2: Send_status state.
This state is activated when the device has the data ready to transfer a data
FIS to the host. When in this state, the device shall request that the
Transport layer transmit a data FIS containing the data. The device
command layer shall request a Data FIS size of no more than 2,048 Dwords
(8KB).
DMAOI0: DMA_in state.
This state is activated when the device has transferred all of the data
requested by the command or has encountered an error that causes the
command to abort before completing the transfer of the requested data.
When in this state, the device shall request that the Transport layer transmit
a Register FIS with the register content as described in the command
description in the ATA/ATAPI-6 standard and the I bit set to one.
