Detected Parity Error (DPE) — RO. Hardwired to 0.
Signaled System Error (SSE) — R/W.
0 = No SERR# signaled by Intel
1 = This bit is set by the ICH7 when it signals SERR# (internally). The SER_EN bit (bit
Received Master Abort (RMA) — R/W.
0 = No master abort received by EHC on a memory access.
1 = This bit is set when EHC, as a master, receives a master abort status on a memory
Received Target Abort (RTA) — R/W.
0 = No target abort received by EHC on memory access.
1 = This bit is set when EHC, as a master, receives a target abort status on a memory
Signaled Target Abort (STA) — RO. This bit is used to indicate when the EHCI function
responds to a cycle with a target abort. There is no reason for this to happen, so this bit
will be
hardwired to 0.
DEVSEL# Timing Status (DEVT_STS) — RO. This 2-bit field defines the timing for
DEVSEL# assertion.
Master Data Parity Error Detected (DPED) — R/W.
0 = No data parity error detected on USB2.0 read completion packet.
1 = This bit is set by the ICH7 when a data parity error is detected on a USB 2.0 read
Fast Back to Back Capable (FB2BC) — RO. Hardwired to 1.
User Definable Features (UDF) — RO. Hardwired to 0.
66 MHz Capable (66 MHz _CAP) — RO. Hardwired to 0.
Capabilities List (CAP_LIST) — RO. Hardwired to 1 indicating that offset 34h contains a
valid capabilities pointer.
Interrupt Status — RO. This bit reflects the state of this function’s interrupt at the
input of the enable/disable logic.
0 = This bit will be 0 when the interrupt is de-asserted.
1 = This bit is a 1 when the interrupt is asserted.
The value reported in this bit is independent of the value in the Interrupt Enable bit.
