Description
On read—PortResetStatus: When this bit is set by a write to
SetPortReset, port reset signaling is asserted. When reset is
completed, this bit is cleared when PortResetStatusChange is set.
This bit cannot be set if CurrentConnectStatus is cleared.
0 — port reset signal is not active
1 — port reset signal is active
On write—SetPortReset: The HCD sets the port reset signaling by
writing a logic 1 to this bit. Writing a logic 0 has no effect. If
CurrentConnectStatus is cleared, this write does not set
PortResetStatus but instead sets ConnectStatusChange. This informs
the driver that it attempted to reset a disconnected port.
On read—PortOverCurrentIndicator: This bit is valid only when the
Root Hub is configured in such a way that overcurrent conditions are
reported on a per-port basis. If per-port overcurrent reporting is not
supported, this bit is set to logic 0. If cleared, all power operations are
normal for this port. If set, an overcurrent condition exists on this port.
This bit always reflects the overcurrent input signal.
0 — no overcurrent condition
1 — overcurrent condition detected
(write) ClearSuspendStatus: The HCD writes a logic 1 to initiate a
resume. Writing a logic 0 has no effect. A resume is initiated only if
PortSuspendStatus is set.
