BIST FIS Successful (BFS): This bit is set any time a
BIST FIS transmitted by the SATA controller receives an
R_OK completion status from the device.
BIST FIS Failed (BFF): This bit is set any time that a
BIST FIS transmitted by the SATA controller receives an
R_ERR completion status from the device.
Port 1 BIST FIS Initiate (P1BFI): When a rising edge is
detected on this bit, the SATA controller will initiate a BIST
FIS to the device on port 1, using the parameters specified
in this register and BFTD1 and BFTD2. The BIST FIS will
only be initiated if a device is present and not in the
partial or slumber states. After a BIST FIS is successfully
completed, software must disable and re-enable PCS.P1E
prior to attempting additional BIST FISes or to return the
SATA controller to a normal operational mode. If the BIST
FIS fails, as indicated by BFF in this register, software can
clear then set this bit to initiate another BIST FIS.
