Description
(read) PortSuspendStatus: This bit indicates whether the port is
suspended or in the resume sequence. It is set by a
SetSuspendState write and cleared when
PortSuspendStatusChange is set at the end of the resume
interval. This bit cannot be set if CurrentConnectStatus is cleared.
This bit is also cleared when PortResetStatusChange is set at the
end of the port reset or when the HC is placed in the USBResume
state. If an upstream resume is in progress, it is propagated to the
HC.
0 — port is not suspended
1 — port is suspended
(write) SetPortSuspend: The HCD sets the PortSuspendStatus
bit by writing logic 1 to this bit. Writing logic 0 has no effect. If
CurrentConnectStatus is cleared, this write action does not set
PortSuspendStatus; instead it sets ConnectStatusChange. This
informs the driver that it attempted to suspend a disconnected
port.
(read) PortEnableStatus: This bit indicates whether the port is
enabled or disabled. The Root Hub can 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 PortEnabledStatusChange to be set. The HCD sets this bit
by writing SetPortEnable and clears it by writing ClearPortEnable.
This bit cannot be set when CurrentConnectStatus is cleared. This
bit is also set at the completion of a port reset when
ResetStatusChange is set or port is suspended when
SuspendStatusChange is set.
0 — port is disabled
1 — port is enabled
(write) SetPortEnable: The HCD sets PortEnableStatus by writing
logic 1. Writing logic 0 has no effect. If CurrentConnectStatus is
cleared, this write does not set PortEnableStatus, but instead sets
ConnectStatusChange. This informs the driver that it attempted to
enable a disconnected port.
(read) CurrentConnectStatus: This bit reflects the current state
of the downstream port.
0 — no device connected
1 — device connected
(write) ClearPortEnable: The HCD writes logic 1 to this bit to clear
the PortEnableStatus bit. Writing logic 0 has no effect.
CurrentConnectStatus is not affected by any write.
Remark: This bit always reads logic 1 when the attached device is
nonremovable (DeviceRemoveable[NDP]).
