PSS
On read—
PortSuspendStatus:
This bit indicates whether the port
is suspended or is in the resume sequence. It is set by a
SetSuspendState write and cleared when PSSC
(PortSuspendStatusChange) is set at the end of the resume
interval. This bit is not set if CCS (CurrentConnectStatus) is
cleared. This bit is also cleared when PRSC
(PortResetStatusChange) 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 will propagate to the Host
Controller.
0 —
port is not suspended
1 —
port is suspended
On write
—SetPortSuspend:
The HCD can set the PSS
(PortSuspendStatus) bit by writing logic 1 to this bit. Writing logic 0
has no effect. If CCS is cleared, this write does not set PSS;
instead it sets CSS. This informs the driver that it attempted to
suspend a disconnected port.
On read
—PortEnableStatus:
This bit indicates whether the port is
enabled or disabled. The Root Hub may clear this bit when an
overcurrent condition, disconnect event, switched-off power or
operational bus error is detected. This change also causes
PortEnabledStatusChange to be set. The HCD can set this bit by
writing SetPortEnable and clear it by writing ClearPortEnable. This
bit cannot be set when CCS (CurrentConnectStatus) is cleared.
This bit is also set at the completion of a port reset when
ResetStatusChange is set or at the completion of a port suspend
when SuspendStatusChange is set.
1
PES
0 —
port is disable
1 —
port is enabled
On write
—SetPortEnable:
The HCD can set PES
(PortEnableStatus) by writing logic 1. Writing logic 0 has no effect.
If CCS is cleared, this write does not set PES, but instead sets
CSC (ConnectStatusChange). This informs the driver that it
attempted to enable a disconnected port.
On read—
CurrentConnectStatus:
This bit reflects the current
state of the downstream port.
0
CCS
0 —
no device connected
1 —
device connected
On write—
ClearPortEnable:
The HCD can write logic 1 to this bit
to clear the PES (PortEnableStatus) bit. Writing logic 0 has no
effect. The CCS (CurrentConnectStatus) bit, on read, is not
affected by any write to ClearPortEnable.
Remark:
This bit always reads logic 1 when the attached device is
nonremovable (DeviceRemoveable[NDP]).
