ICH8 Family Datasheet
AIR—AHCI Index Register (D31:F2)
Address Offset: Primary: BAR + 10h
Default Value:
This register is available only when CC.SCC is not 01h.

Error (ERR) — R/WC. The ERR field contains error information for use by host software
in determining the appropriate response to the error condition.
If one or more of bits 11:8 of this register are set, the controller will stop the current
transfer.

Index (INDEX)— R/W. This Index register is used to select the DWord offset of the
Memory Mapped AHCI register to be accessed. A Dword, Word or Byte access is
specified by the active byte enables of the I/O access to the Data register.
Reserved
Internal Error (E): The SATA controller failed due to a master or target abort
when attempting to access system memory.
Protocol Error (P): A violation of the Serial ATA protocol was detected.
Note: The ICH8 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
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
recovered by the interface.
Reserved
Recovered Communications Error (M): Communications between the device
and host was temporarily lost but was re-established. This can arise from a device
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
recovered by the interface through a retry operation or other recovery action.
