Revision ID — RO. Refer to the Intel
the value of the Revision ID Register
Detected Parity Error (DPE) — R/WC.
0 = No parity error detected.
1 = Set when a data parity error data parity error is detected on writes to the UHCI register space or
Reserved as 0b. Read Only.
Received Master Abort (RMA) — R/WC.
0 = No master abort generated by USB.
1 = USB, as a master, generated a master abort.
Reserved. Always read as 0.
Signaled Target Abort (STA) — R/WC.
0 = ICH6 did Not terminate transaction for USB function with a target abort.
1 = USB function is targeted with a transaction that the ICH6 terminates with a target abort.
DEVSEL# Timing Status (DEV_STS) — RO. This 2-bit field defines the timing for DEVSEL#
assertion. These read only bits indicate the ICH6's DEVSEL# timing when performing a positive
decode. ICH6 generates DEVSEL# with medium timing for USB.
Data Parity Error Detected (DPED) — RO. Hardwired to 0.
Fast Back to Back Capable (FB2BC) — RO. Hardwired to 1.
User Definable Features (UDF) — RO. Hardwired to 0.
66 MHz Capable — RO. Hardwired to 0.
Capabilities List — RO. Hardwired to 0.
Interrupt Status — RO. This bit reflects the state of this function’s interrupt at the input of the
enable/disable logic.
0 = Interrupt is de-asserted.
1 = Interrupt is asserted.
The value reported in this bit is independent of the value in the Interrupt Enable bit.
Reserved
on read completions returned to the host controller.
