Description
ConnectStatusChange: This bit is set whenever a connect or
disconnect event occurs. The HCD writes a logic 1 to clear this bit.
Writing a logic 0 has no effect. If CurrentConnectStatus is cleared
when a SetPortReset, SetPortEnable, or SetPortSuspend write
occurs, this bit is set to force the driver to reevaluate the connection
status since these writes should not occur if the port is disconnected.
0 — no change in CurrentConnectStatus
1 — change in CurrentConnectStatus
Remark: If bit DeviceRemovable[NDP] is set, this bit is set only after a
Root Hub reset to inform the system that the device is attached.
reserved
On read—LowSpeedDeviceAttached: This bit indicates the speed of
the device connected to this port. When set, a low-speed device is
connected to this port. When clear, a full-speed device is connected to
this port. This field is valid only when the CurrentConnectStatus is set.
0 — full-speed device attached
1 — low-speed device attached
On write—ClearPortPower: The HCD clears bit PortPowerStatus by
writing a logic 1 to this bit. Writing a logic 0 has no effect.
On read—PortPowerStatus: This bit reflects the port power status,
regardless of the type of power switching implemented. This bit is
cleared if an overcurrent condition is detected.
The HCD sets this bit by writing SetPortPower or SetGlobalPower.
The HCD clears this bit by writing ClearPortPower or
ClearGlobalPower. Which power control switches are enabled is
determined by PowerSwitchingMode.
In the global switching mode (PowerSwitchingMode = 0), only
Set/ClearGlobalPower controls this bit. In per-port power switching
(PowerSwitchingMode = 1), if bit PortPowerControlMask[NDP] for the
port is set, only Set/ClearPortPower commands are enabled. If the
mask is not set, only Set/ClearGlobalPower commands are enabled.
When port power is disabled, CurrentConnectStatus,
PortEnableStatus, PortSuspendStatus, and PortResetStatus should
be reset.
0 — port power is off
1 — port power is on
On write—SetPortPower: The HCD writes a logic 1 to set
bit PortPowerStatus. Writing a logic 0 has no effect.
Remark: This bit always reads logic 1 if power switching is not
supported.
