HcRhPortStatus[4:1] register
The HcRhPortStatus[4:1] 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 reflects the port status. 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 is postponed until the
transaction completes. Always write logic 0 to the reserved bits. The bit allocation of the
register is given in
Table 84
.
[1]
The reserved bits should always be written with the reset value.

OverCurrentIndicator
: 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—
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), logic 1 is written to this bit to turn off power to
all ports (clear PortPowerStatus). In per-port power mode, it clears
PortPowerStatus only on ports whose PortPowerControlMask bit is not set.
Writing logic 0 has no effect.
