Description
Detected Parity Error. This bit is set whenever the USB detects a parity error, even if
the Parity Error (response) detection enable bit (Index 04h[6]) is disabled. Write 1 to
clear.
SERR# Status. This bit is set whenever the USB detects a PCI address error. Write 1
to clear.
Received Master Abort Status. This bit is set when the USB, acting as a PCI master,
aborts a PCI bus memory cycle. Write 1 to clear.
Received Target Abort Status. This bit is set when a USB generated PCI cycle (USB
is the PCI master) is aborted by a PCI target. Write 1 to clear.
Signaled Target Abort Status. This bit is set whenever the USB signals a target abort.
Write 1 to clear.
DEVSEL# Timing (Read Only). These bits indicate the DEVSEL# timing when per-
forming a positive decode. Since DEVSEL# is asserted to meet the medium timing,
these bits are encoded as 01.
Data Parity Reported. Set to 1 if the Parity Error bit (Command Register bit 6) is set,
and USB detects PERR# asserted while acting as PCI master (whether PERR# was
driven by USB or not).
Fast Back-to-Back Capable (Read Only). USB does support fast back-to-back trans-
actions when the transactions are not to the same agent. This bit is always 1.
Reserved. Set to 0.
