Description
0 = No Parity error detected by SATA controller.
1 = SATA Controller detects a parity error on its interface.
®
This bit is set by the Intel
SERR# (internally). The SERR_EN bit (bit 8 in the Command
Register) must be '1' for this bit to be set. The following
conditions can cause the generation of SERR#:
A parity error is seen on address, command, or data (if the
data was targeting the EHC) on the internal interface to the
USBe host controller due to a parity error on Hub Interface
and bit 6 of the Command register is set to 1.
An EHC-initiated memory read results in a completion packet
with a status other than successful on Hub Interface. The
SERR on Aborts Enable bit (bit 3, offset 84h) must also be set
in this case.
Software clears this bit by writing a '1' to this bit location.
0 = 0 Cleared by writing a '1' to it.
1 = Bus Master IDE interface function, as a master, generated
a master-abort.
Set when the SATA Controller receives a target abort to a
cycle it generated.
Reserved as '0'.
01 = Hardwired; Controls the device select time for the SATA
Controller's PCI interface.
Set when the SATA Controller, as a master, either detects a
parity error or sees the parity error line asserted, and the
parity error response bit (bit 6 of the command register) is
®
set. For the Intel 6300ESB ICH, this bit may only be set on
read completions when there is a parity error.
Reserved as '1'.
Reserved as '0'.
Reserved as '1'.
Indicates the presence of a capabilities list. This bit is
hardwired to a '1' indicating the presence of a valid
capabilities pointer at offset 34h.
