HcRhPortStatus[1:2] register: bit description
Description
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
On write ClearSuspendStatus: The HCD writes logic 1 to initiate a resume.
Writing logic 0 has no effect. A resume is initiated only if PortSuspendStatus
(PSS) is set.
On read PortSuspendStatus: This bit indicates whether the port is
suspended or is in the resume sequence. It is set by a PortSuspendStatus
write and cleared when PortSuspendStatusChange (PSSC) is set at the end
of the resume interval. This bit cannot be set if CurrentConnectStatus (CCS)
is cleared. This bit is also cleared when PortResetStatusChange (PRSC) is
set at the end of the port reset or when the host controller is placed in the
USBResume state. If an upstream resume is in progress, it should propagate
to the host controller.
0 — port is not suspended
1 — port is suspended
On write SetPortSuspend: The HCD sets the PortSuspendStatus (PSS) bit
by writing logic 1 to this bit. Writing logic 0 has no effect. If
CurrentConnectStatus (CCS) is cleared, this write does not set
PortSuspendStatus (PSS); instead it sets ConnectStatusChange (CSC). This
informs the driver that it attempted to suspend a disconnected port.
On read PortEnableStatus: This bit indicates whether the port is enabled or
On read CurrentConnectStatus: This bit reflects the current state of the
On read PortOverCurrentIndicator: This bit is valid only when the root hub
disabled. The root hub may clear this bit when an overcurrent condition,
disconnect event, switched-off power or operational bus error, such as
babble, is detected. This change also causes PortEnableStatusChange to be
set. The HCD sets this bit by writing SetPortEnable and clears it by writing
ClearPortEnable. This bit cannot be set when CurrentConnectStatus (CCS)
is cleared. This bit is also set, if it is not already, at the completion of a port
reset when PortResetStatusChange is set or port suspend when
PortSuspendStatusChange is set.
0 — port is disabled
1 — port is enabled
On write SetPortEnable: The HCD sets PortEnableStatus (PES) by writing
logic 1. Writing logic 0 has no effect. If CurrentConnectStatus (CCS) is
cleared, this write does not set PortEnableStatus (PES), but instead sets
ConnectStatusChange (CSC). This informs the driver that it attempted to
enable a disconnected port.
downstream port.
0 — no device connected
1 — device connected
On write ClearPortEnable: The HCD writes logic 1 to this bit to clear the
PortEnableStatus (PES) bit. Writing logic 0 has no effect.
CurrentConnectStatus (CSC) is not affected by any write.
Remark: This bit always reads logic 1 when the attached device is
nonremovable (DeviceRemovable[NDP]).
