Table 33.
The HcRhPortStatus[1:2] register is used to control and report port events on a per-port
basis. NumberDownstreamPorts represents the number of HcRhPortStatus registers that
are implemented in hardware. The lower word is used to reflect the port status, whereas
the upper word reflects the status change bits. Some status bits are implemented with
special write behavior. If a transaction (token through handshake) is in progress when a
write to change port status occurs, the resulting port status change must be postponed
until the transaction completes. Reserved bits should always be written logic 0.

Description
reserved
OverCurrentIndicator: This bit reports overcurrent conditions when
global reporting is implemented. When set, an overcurrent condition
exists. When clear, all power operations are normal. If per-port
overcurrent protection is implemented this bit is always logic 0.
On read—LocalPowerStatus: The Root Hub does not support the
local power status feature. Therefore, this bit is always read as logic 0.
On write—ClearGlobalPower: In global power mode
(PowerSwitchingMode = 0), this bit is written to logic 1 to turn off
power to all ports (clear PortPowerStatus). In per-port power mode, it
clears PortPowerStatus only on ports whose
bit PortPowerControlMask is not set. Writing a logic 0 has no effect.
