SATA Controller Registers (D31:F2)
Bit
Description
8
Transient Data Integrity Error (T): A data integrity error occurred that was not
recovered by the interface.
7:2 Reserved
Recovered Communications Error (M). Communications between the device and
host was temporarily lost but was re-established. This can arise from a device
1 temporarily being removed, from a temporary loss of Phy synchronization, or from
other causes and may be derived from the PhyNRdy signal between the Phy and Link
layers.
0
Recovered Data Integrity Error (I). A data integrity error occurred that was
recovered by the interface through a retry operation or other recovery action.

Note:
AHCI Registers (D31:F2)
These registers are AHCI-specific and available when the PCH is properly configured.
The Serial ATA Status, Control, and Error registers are special exceptions and may be
accessed on all PCH components if properly configured; see Section 14.3 for details.
The memory mapped registers within the SATA controller exist in non-cacheable
memory space. Additionally, locked accesses are not supported. If software attempts to
perform locked transactions to the registers, indeterminate results may occur. Register
accesses shall have a maximum size of 64-bits; 64-bit access must not cross an 8-byte
alignment boundary. All memory registers are reset by Function Level Reset unless
specified otherwise.
The registers are broken into two sections – generic host control and port control. The
port control registers are the same for all ports, and there are as many registers banks
as there are ports.
