(read)PortPowerStatus
This bit reflects the port’s power status, regardless of the type of power
switching implemented. This bit is cleared if an overcurrent condition is
detected. HCD sets this bit by writing SetPortPower or
SetGlobalPower. HCD clears this bit by writing ClearPortPower or
ClearGlobalPower. Which power control switches are to be enabled is
determined by PowerSwitchingMode and
PortPowerControlMask[NDP]. In global switching mode
(PowerSwitchingMode = 0), only Set/ClearGlobalPower controls this
bit. In per-port power switching (PowerSwitchingMode = 1), if the
PortPowerControlMask[NDP] bit 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 off
1: Port power on
(write)SetPortPower
HCD writes a 1 to set the PortPowerStatus bit. Writing a 0 has no
effect.
Note:
This bit always reads 1 if power switching is not supported.
(read)PortResetStatus
When this bit is reset by a write to SetPortReset, port reset signaling is
asserted. After reset is complete, 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
(write)SetPortReset
HCD sets the port reset signaling by writing a 1 to this bit. Writing a 0
has no effect. If CurrentConnectStatus is cleared, this write does not
set PortResetStatus, but instead sets CurrentConnectStatusChange.
This informs the driver that it attempted to reset a disconnected port.
