SATA Controller Registers (D31:F2)
Bit
10b to 8b Decode Error (B). Indicates that one or more 10b to 8b decoding errors
19
occurred.
18 Comm Wake (W). Indicates that a Comm Wake signal was detected by the Phy.
17 Phy Internal Error (I). Indicates that the Phy detected some internal error.
PhyRdy Change (N): When set to 1, this bit indicates that the internal PhyRdy signal
changed state since the last time this bit was cleared. In the PCH, this bit will be set
16 when PhyRdy changes from a 0 -> 1 or a 1 -> 0. The state of this bit is then reflected in
the PxIS.PRCS interrupt status bit and an interrupt will be generated if enabled.
Software clears this bit by writing a 1 to it.
15:12 Reserved
Internal Error (E). The SATA controller failed due to a master or target abort when
11
attempting to access system memory.
Protocol Error (P). A violation of the Serial ATA protocol was detected.
10 Note: The PCH does not set this bit for all protocol violations that may occur on the
SATA link.
Persistent Communication or Data Integrity Error (C). A communication error
that was not recovered occurred that is expected to be persistent. Persistent
9
communications errors may arise from faulty interconnect with the device, from a
device that has been removed or has failed, or a number of other causes.
Transient Data Integrity Error (T): A data integrity error occurred that was not
8
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.
Recovered Data Integrity Error (I). A data integrity error occurred that was
0
recovered by the interface through a retry operation or other recovery action.
