PPS
On read, Port Power Status: This bit reects the port power status, regardless of the type of
power switching implemented. This bit is cleared if an overcurrent condition is detected. The
HCD can set this bit by writing Set Port Power or Set Global Power. The HCD can clear this bit
by writing Clear Port Power or Clear Global Power. Power Switching Mode and
PortPowerControlMask[NDP] determine which power control switches are enabled. In global
switching mode (Power Switching Mode = 0), only Set/Clear Global Power controls this bit. In
the per-port power switching (Power Switching Mode = 1), if the PortPowerControlMask[NDP]
bit for the port is set, only Set/Clear Port Power commands are enabled. If the mask is not set,
only Set/Clear Global Power commands are enabled.
When port power is disabled, bits CCS (Current Connect Status), PES (Port Enable Status),
PSS (Port Suspend Status) and PRS (Port Reset Status) should be reset.
0 — Port power is off.
1 — Port power is on.
On write, Set Port Power: The HCD can write logic 1 to set the PPS bit. Writing logic 0 has no
effect.
Remark: This bit always reads logic 1 if power switching is not supported.

PRS
On read, Port Reset Status: When this bit is set by a write to Set Port Reset, port reset
signaling is asserted. When reset is completed and PRSC is set, this bit is cleared.
0 — Port reset signal is inactive.
1 — Port reset signal is active.
On write, Set Port Reset: The HCD can set the port reset signaling by writing logic 1 to this bit.
Writing logic 0 has no effect. If CCS is cleared, this write does not set PRS (Port Reset Status)
but instead sets CCS. This informs the driver that it attempted to reset a disconnected port.
3
POCI
On read, Port Overcurrent Indicator: This bit is valid only when the root hub is congured to
show overcurrent conditions are reported on a per-port basis. If the per-port overcurrent
reporting is not supported, this bit is set to logic 0. If cleared, all power operations are normal
for this port. If set, an overcurrent condition exists on this port.
0 — No overcurrent condition.
1 — Overcurrent condition detected.
On write, Clear Suspend Status: The HCD can write logic 1 to initiate a resume. Writing
logic 0 has no effect. A resume is initiated only if PSS (Port Suspend Status) is set.
2
PSS
On read, Port Suspend Status: This bit indicates whether the port is suspended or is in the
resume sequence. It is set by a Set Suspend State write and cleared when PSSC (Port
Suspend Status Change) is set at the end of the resume interval. This bit is not set if CCS
(Current Connect Status) is cleared. This bit is also cleared when PRSC is set at the end of the
port reset or when the Host Controller is placed in the USBRESUME state. If an upstream
resume is in progress, it will propagate to the Host Controller.
0 — Port is not suspended.
1 — Port is suspended.
On write, Set Port Suspend: The HCD can set the PSS (Port Suspend Status) bit by writing
logic 1 to this bit. Writing logic 0 has no effect. If CCS is cleared, this write does not set PSS;
instead it sets CSS. This informs the driver that it attempted to suspend a disconnected port.
