register + 54h)
The HcRhPortStatus[1:4] register is used to control and report port events on a per-port
basis. NumberofDownstreamPort represents the number of HcRhPortStatus registers that
are implemented in hardware. The lower word reflects the port status. The upper word
reflects 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 is postponed until the transaction
completes. Always write logic 0 to the reserved bits. The bit allocation of the register is
given in

Overcurrent Indicator: This bit reports overcurrent conditions when global
reporting is implemented. When set, an overcurrent condition exists. When
cleared, all power operations are normal. If the per-port overcurrent protection
is implemented, this bit is always logic 0.
On read Local Power Status: The root hub does not support the local power
status feature. Therefore, this bit is always read as logic 0.
On write Clear Global Power: In global power mode (Power Switching
Mode = 0), logic 1 is written to this bit to turn off power to all ports (clear Port
Power Status). In per-port power mode, it clears Port Power Status only on
ports whose Port Power Control Mask bit is not set. Writing logic 0 has no
effect.
