SActive bits
The bits of this register may be written with a 1, but are cleared if the corresponding bits of the second dword of a
FIS are set when the SDevice Bits FIS is received. All 32 bits may be cleared by writing 0x0000_0000 to the
register; individual bits may not be cleared except by the hardware.

This register contains bits for controlling Serial ATA power management, ComWake, loopback modes, and FIS
transfers.
Bit [31]: FIS_Done (R/W) – This bit is used to indicate to the link logic that all the data for the Transparent
FIS has been transferred and that the link can proceed to close out the FIS. This is used in Transparent
FIS transmission. Please refer to the “FIS Support” section on page 85 for more details.
Bit [30]: Transmit_FIS (W)– This bit is used to signal the link logic to start the process of transmitting a
Transparent FIS. Please refer to the “FIS Support” section on page 85 for more details.
Bit [29]: Transmit_OK (R)– This bit is used in Transparent FIS transmission. It is used by the link to signal
to the host that the current Transparent FIS has been successfully transferred to the device, and that R_OK
has been received.
Bit [28]: IFIS_OK (R)– This bit is used in the reception of Interlocked FISes. This bit is set by the link logic
to inform the host that the current Interlocked FIS has been successfully received with no errors.
Bit [27]: IntrlckFIS (R)– This bit is set to indicate to the host driver that the link has detected an the arrival
of an interlocked FIS and that the host should set up the DMA engine to start transfer of data
Bit [26]: Reject_IFIS (W)– This bit is set by the host driver to indicate to the link that the current Interlocked
FIS should be rejected. The link logic will respond to the device with an R_ERR when the complete FIS has
been received.
Bit [25]: Accept_IFIS (W)– This bit is set by the host driver to indicate to the link that the current interlocked
FIS should be accepted. The link logic will respond to the device with R_OK
Bit [24]: Rx_IFIS (W)– This bit is set by the host driver to inform the link/transport logic that the host has
set up the DMA engine to transfer the incoming Interlocked FIS and that the DMA cycles can begin
Bit [23]: SDB (R) – This bit indicates that a Set Device Bits FIS has been received
Bit [22]: pterr (R) – This bit indicates that a Protocol Error has occurred. An interrupt will be generated if bit
20 of SIEN is set.
Bit [21]: Scr_dis (R/W)– This bit disables the scrambling of data on the serial ATA bus. This is used only for
debugging purposes and should not be changed by the user
